BEST BEST-CB223RH-630-5x4.5 – Frequently Asked Questions

1) Will the BEST CB223 hinge work on a beveled edge door?
That's exactly what the CB223 is built for. It uses a different door plate configuration specifically for beveled edge doors, so if your door edge is beveled rather than square, this is the correct version. Short door plate options are available where a concealed holder or closer occupies the top of the door.
2) What size and handing does the BEST CB223 pivot reinforced hinge come in?
The CB223 is made in one size, 4.5 x 5 inches, in 630 satin stainless steel, and it is handed. Order left hand or right hand to match the door swing. Because the pivot and butt leaves share a pin, there is no field-reversing it, so get the handing right on the order.
3) Why would I use a pivot reinforced hinge instead of a standard ball bearing butt hinge?
A pivot reinforced hinge is for the top of a door that gets abused. The CB223 combines a pivot and a butt hinge in one interlocked unit, which anchors and reinforces the door and frame and transfers the stress into the top hinge instead of tearing out the leaf screws. On an ordinary opening, a plain full mortise bearing hinge like the Don-Jo BB94545 in stainless steel is all you need. Use the reinforced type where doors are kicked, carted into, or slammed, such as stairwells, service corridors, and loading areas.
4) Do I need three CB223 hinges per door, or just one at the top?
One. The CB223 is the reinforcing top hinge, designed so door and frame stresses transfer into it. The rest of the hinge positions on the leaf take standard heavy weight full mortise hinges of the same 4-1/2 inch width and finish, such as the McKinney TCA3386 heavy weight square corner hinge, so the leaf sits plumb and the finishes match.
5) Will the CB223 fit an existing square corner hinge mortise?
The CB223 has square corners, so it sits in a routed square corner pocket rather than a radius corner one. Be aware it is not a straight drop-in for a plain butt hinge: it is 4.5 x 5 inches with a pivot leaf that mounts to the top of the door, so the frame and door top both need prep. Follow the BEST hinge templates and installation instructions for the cutouts.
6) I have a square edge door, not beveled. Is the CB223 still the right hinge?
No. The CB223 door plate is configured for a beveled door edge. On a square edge door you want the square edge version of the concealed bearing pivot reinforced hinge, or if you do not need the pivot reinforcement at all, a heavy weight concealed bearing full mortise hinge such as the Stanley Security CB199.
7) Which concealed bearing hinge should I use on a standard weight commercial door instead of the BEST CB223?
For a door that does not carry heavy weight loads, the Stanley Security CB1960R full mortise concealed bearing standard weight hinge is the concealed bearing option in the medium duty class. It keeps the concealed bearing operation but is built to standard weight rather than the heavy weight construction of the BEST CB223, which uses heavy weight gauges to increase bearing surface area and is rated heavy duty. The CB1960R is in the Architectural Hinges series. Choose the CB223 where the door is heavy or exposed to jarring and abusive handling, and the CB1960R where the opening is an ordinary commercial door at standard weight.
8) What is the closest equivalent to a BEST CB223 hinge from another manufacturer?
The nearest peer is the Stanley Security CB199 full mortise concealed bearing heavy weight hinge, which matches the CB223 on the three things that define it: full mortise mounting, concealed bearing, and heavy duty rating. The CB223 itself is a concealed bearing, heavy duty full mortise hinge with square corners and 5 knuckles. The CB199 is part of the Architectural Hinges series. The difference to confirm before ordering is that the CB223 is a pivot reinforced design, combining a pivot and butt hinge in one interlocked unit sharing the same pin for beveled edge doors subject to jarring or abusive handling; the CB199 is a straight concealed bearing hinge without the pivot reinforcement. If the frame and door are being anchored against abuse, the pivot reinforced unit is the matching part.
9) Is a ball bearing hinge the same as the BEST CB223 concealed bearing hinge?
No. The BEST CB223 uses a concealed bearing, where the bearing is enclosed within the knuckle. A ball bearing hinge such as the McKinney TCA3386 square corner 5 knuckle full mortise hinge, 4-1/2 by 4-1/2, heavy weight, or the Hager WTBB1168 4-1/2 by 6 full mortise ball bearing wide throw hinge, both of which are heavy duty, carries the load on visible bearing races between the knuckles. Both types are full mortise and both can be had in heavy duty, so the load class can match; what differs is the bearing construction and its appearance in the knuckle. If a specification calls out concealed bearing, a ball bearing hinge does not satisfy it even at the same weight class.
10) What hinge do I use if the door needs to swing clear of the opening rather than a pivot reinforced hinge?
For an opening where the door leaf has to swing clear of the frame to recover the full clear width, the Hager 1260 full mortise swing clear hinge with 5 knuckle plain bearing design is the part to specify. It is heavy duty and uses a plain bearing. The BEST CB223 is a pivot reinforced hinge whose purpose is different: it anchors and reinforces doors and frames exposed to damage from abuse by transferring stresses to the top hinge, and it carries a concealed bearing. Where clear width at the opening is the requirement, such as an accessible route through a corridor door, the swing clear geometry is what answers it; where abuse resistance on a heavy door is the requirement, the pivot reinforced hinge is.
11) Does the CB223 hinge bind or sag the way a pivot alone can?
The pivot and butt hinge share one pin in the CB223, which holds the two in alignment and prevents sidewise motion of either the pivot or the butt leaves. That is the point of the interlocked design: you get pivot-level reinforcement without the alignment drift of a separate pivot and hinge set.
12) What is the difference between concealed bearing and ball bearing hinges for a commercial door?
Concealed bearing hinges, like the CB223, hide the bearing inside the knuckle so the barrel reads as a clean five knuckle profile and the bearing is protected from dirt and moisture. Ball bearing hinges show the bearing races between knuckles, as on the Don-Jo BB74545 or the Hager WTBB1168 heavy weight wide throw. Both carry weight; concealed is chosen where appearance matters or the opening is exposed. Plain bearing hinges such as the Hager 1279 are a lighter-duty option with no bearing at all.
13) Can I get the CB223 with electric through-wire for an electrified lock?
The CB223 is a mechanical reinforcing hinge with no wire transfer. If you need power across the opening through a hinge, use an electric through-wire hinge such as the ACSI 5BB1, a 4-1/2 by 4-1/2 inch five knuckle ball bearing full mortise hinge with a concealed four-wire, 28 gauge transfer. Many jobs use the through-wire hinge in one position and the reinforcing hinge in another.
14) I need a hinge that swings the door fully clear of the opening for wheelchair access. Is this it?
No, the CB223 is a standard full mortise hinge and the door leaf stays in the opening when open. For clearing the full width, use a swing clear hinge such as the Hager 1260, a full mortise swing clear hinge with a five knuckle plain bearing design.
15) Can I put a standard duty full mortise hinge on the opening instead of the BEST CB223?
A standard duty hinge is a different class of part. The Don-Jo BB94545 full mortise ball bearing hinge 4-1/2 by 4-1/2 in stainless steel with square corner and the McKinney TCA2314 square corner 5 knuckle full mortise hinge, 4-1/2 by 4-1/2, are both standard duty. The BEST CB223 is heavy duty, with heavy weight gauges that increase the available bearing surface area, and it is a commercial hinge built for doors subject to jarring or abusive handling. On a low traffic interior door at standard weight, a standard duty hinge is the corresponding part; on the heavy or abused opening the CB223 is designed for, match the heavy duty class instead.
16) I need to run power through the door for an electric lock. Will the BEST CB223 do that?
The BEST CB223 is a mechanical pivot reinforced hinge with a concealed bearing; power transfer is a separate function. For an opening that has to carry current to the door, the ACSI 5BB1 Ives 5 knuckle ball bearing full mortise hinge 4-1/2 by 4-1/2 with concealed electric through-wire is a 4 wire 28 gauge electric through-wire hinge in the 1100 Series. The two are not interchangeable: the ACSI hinge provides the wire path for an electrified lock or exit device, while the CB223 provides reinforcement for doors and frames exposed to damage from abuse. On an electrified heavy door, the electric hinge normally takes one leaf position and mechanical hinges fill the rest.
17) The door frame is set back from the wall and the door has to clear trim. Which hinge handles that?
That calls for a wide throw hinge. The Hager WTBB1168 is a 4-1/2 by 6 full mortise ball bearing wide throw hinge, heavy weight with 5 knuckles and rated heavy duty; the extra leaf width throws the door further off the frame so it clears projecting trim or a deep reveal. The BEST CB223 is a heavy duty full mortise hinge in a 4.5 inch by 5 inch size, so it does not provide that added throw. Both are heavy duty and full mortise, so the load class is comparable; the deciding dimension is leaf width against the reveal you measured.
18) I want to standardize stainless steel hinges across a facility. How does the BEST CB223 compare to the Don-Jo stainless option?
Both are stainless steel full mortise hinges with square corners. The BEST CB223 is a stainless steel concealed bearing hinge in 630 satin stainless steel, heavy duty, with 5 knuckles and square corners. The Don-Jo BB94545 full mortise ball bearing hinge 4-1/2 by 4-1/2 is stainless steel with a square corner and is standard duty. For a facility standard, the two differences that matter are bearing type, concealed versus ball bearing, and duty class, heavy versus standard. Many facilities use the heavy duty concealed bearing hinge on high traffic and abused openings and the standard duty stainless hinge on ordinary interior doors, which keeps the stainless appearance consistent while matching each opening to its load.
19) The replacement hinge has to fit an existing 4-1/2 by 4 inch mortise. Can I use the BEST CB223?
Check the cutout before ordering. The BEST CB223 is supplied in a 4.5 inch by 5 inch size, so the leaf is 5 inches tall and will not drop into a shallower existing mortise without rework. The Don-Jo BB74540 full mortise ball bearing hinge in satin chrome is a 4-1/2 by 4 inch hinge and is standard duty, which is the size match for that prep. Where the opening genuinely needs the heavy duty pivot reinforced construction of the CB223, plan on routing the door and frame to the larger leaf using the manufacturer templates rather than forcing a fit.
20) Do I need a handed hinge like the BEST CB223, or will a non-handed mortise hinge work?
It depends on which part you are specifying. The BEST CB223 is available in left hand and right hand configurations because it is a pivot reinforced unit whose door plate is configured for beveled edge doors, so the handing of the door swing has to be confirmed before ordering. Conventional full mortise butt hinges such as the McKinney TCA2317 square corner 5 knuckle full mortise hinge, 4-1/2 by 4-1/2, standard duty, are symmetrical leaves and are ordered without handing. If you are replacing a plain butt hinge and no pivot reinforcement is required, handing is not part of the order; if you are specifying the CB223, it is.
21) What finish is the BEST CB223 hinge, and will it match my other stainless door hardware?
630 satin stainless steel, which is the standard satin stainless finish on commercial door hardware and pairs with 630 hinges, push plates, and exit device trim. It is the only finish the CB223 is offered in. For the non-reinforced positions on the same leaf, the Don-Jo BB94545 is a stainless steel square corner full mortise hinge.
22) What is the lighter weight version of the BEST concealed bearing hinge?
If the door does not need heavy weight gauges, the Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge rated medium duty. It gives you the same hidden bearing look in a lighter hinge. Keep the CB223 for the top position on doors taking abuse, where the pivot reinforcement is the reason to buy it.
23) Is there a plain bearing hinge that serves the same commercial openings as the BEST CB223?
The Hager 1279 full mortise plain bearing commercial hinge with 5 knuckles is a medium duty commercial hinge, and the Hager 1541 full mortise plain bearing hinge is a residential hinge in stainless steel with a 5 knuckle design. Both use a plain bearing rather than the concealed bearing in the BEST CB223, which is heavy duty and built for commercial use with heavy weight gauges that increase bearing surface area for friction reduction. Plain bearing hinges suit lower frequency openings; the concealed bearing heavy weight hinge is the one specified where the door is heavy and the cycle count is high.
24) What is the difference between the brass and steel Don-Jo ball bearing hinges and the BEST CB223 for a corrosive environment?
Material is the deciding factor. The BEST CB223 is stainless steel with a 630 satin stainless steel finish, which the product describes as providing corrosion resistance for commercial applications, and it is heavy duty. The Don-Jo BB84545 full mortise ball bearing hinge 4-1/2 by 4-1/2 is brass in satin chrome, and the Don-Jo BB74545 full mortise ball bearing hinge 4-1/2 by 4-1/2 is steel with a square corner and 5 knuckles; both are standard duty. For a washdown area, a coastal exterior, or a pool enclosure, the stainless construction is the one to hold to; the brass and steel hinges are the choices for ordinary dry interior openings.
