BEST BEST-CB168-652-4.5x4.5 – Frequently Asked Questions

1) What sizes and finishes does the BEST CB168 full mortise hinge come in?
The CB168 is offered in three sizes, 4-1/2 x 4-1/2, 4-1/2 x 5, and 5 x 5 inches, and each size is available in all three finishes: 641 oxidized bronze, 651 bright chrome, and 652 satin chrome. That is the full matrix, nine combinations. Pick the leaf size that matches what came out of the door; a 4-1/2 inch leaf will not cover a 5 inch mortise pocket.
2) Will the BEST CB168 hinge fit a hollow metal door and frame, or is it only for wood?
Both. The CB168 is made with template screw hole locations, so the hole pattern drops into standard hollow metal frame and door prep as well as into wood doors and frames. Being a full mortise hinge, it needs both the door edge and the frame rabbet mortised for the leaves; it is not a surface applied hinge.
3) Do I need to order a left hand and right hand version of the CB168 hinge?
No. Handing is not a factor here. The CB168 has reversible flush tips and a reversible pin, so the same hinge works on either hand of door. Order by size and finish only.
4) Can I take the door down without unscrewing the CB168 hinges?
Yes, the pin comes out. The CB168 uses a removable pin with a hole in the bottom tip, so you drive it up from underneath with a pin punch and lift the door off with the leaves still screwed to the door and frame. Worth knowing on the security side: a removable pin is not a non-removable-pin (NRP) hinge, so on an out-swinging exterior door where the barrel is on the unsecured side, spec an NRP hinge instead.
5) Are the CB168 hinges square corner or radius corner?
Square corners. That matters if you are replacing hinges in an existing door: a square corner hinge will not sit right in a mortise that was routed with a 1/4 or 5/8 inch radius by a router template, and a radius corner hinge leaves gaps in a chiselled square pocket. Look at the corner of the existing mortise before ordering. Hollow metal frames are typically square prepped, which suits the CB168.
6) Can I swap a CB168 straight in for the hinges already on my commercial door?
Often yes, if three things line up: the existing mortise measures 4-1/2 x 4-1/2, 4-1/2 x 5 or 5 x 5 inches, the mortise corners are square rather than radiused, and the hinge is a full mortise type with leaves let into both the door edge and the frame. The CB168 is templated, so the screw holes land on standard hollow metal and wood prep. Measure a leaf off the door before ordering rather than eyeballing it.
7) Is there a lighter concealed bearing hinge for interior office doors that do not need heavy weight?
The Stanley Security CB1960R is a full mortise concealed bearing standard weight hinge rated medium duty, in the same Architectural Hinges series as the CB168. It keeps the concealed bearing construction and full mortise prep while carrying a medium duty rating instead of the CB168 heavy duty rating, which suits interior office and corridor doors that are lighter and see less traffic than a building entrance.
8) I need to run power through the door for an electric strike or exit device. Does the CB168 do that?
The CB168 is a mechanical hinge with a removable pin and concealed bearings; it does not carry wiring. For a powered opening, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge, 4-1/2 by 4-1/2, with concealed electric through-wire in a 4 wire 28 gauge configuration, from the 1100 Series. It transfers power from frame to door at the hinge, which is what an electrified lock or exit device on the door leaf requires. Its 4-1/2 by 4-1/2 full mortise footprint matches one of the CB168 sizes.
9) I need a heavy weight hinge that lets a wheelchair pass the full door opening width. What do I use instead of a standard full mortise hinge?
The Hager 1260 is a full mortise swing clear hinge, heavy duty, with a 5 knuckle plain bearing design. A swing clear hinge carries the door leaf clear of the opening when the door swings back, recovering the width the door thickness would otherwise take out of the clear passage. The CB168 is a conventional full mortise hinge, so it holds the door in the opening; if the clear width on a healthcare corridor is the governing dimension, the swing clear geometry is the difference that matters. Note the 1260 runs plain bearing rather than the concealed bearing of the CB168.
10) What heavy weight hinge should I use if the door has to clear a deep trim or casing that a 4-1/2 by 4-1/2 hinge will not swing past?
The Hager WTBB1168 is a wide throw ball bearing hinge, 4-1/2 inch by 6 inch, heavy weight with 5 knuckles. The extra leaf width on a wide throw hinge carries the door further off the frame than the 4-1/2 by 4-1/2, 4-1/2 by 5 and 5 by 5 sizes the CB168 comes in, which is what an opening with deep trim or a return wall needs. It stays at the heavy weight level and 5 knuckle count matching the CB168.
11) What is the closest equivalent to the BEST CB168 heavy weight concealed bearing hinge?
The Stanley Security CB199 is the nearest match. It is also a full mortise concealed bearing heavy weight hinge in the Architectural Hinges series, the same series and heavy duty level as the CB168, and it uses the same concealed bearing full mortise mounting approach. For a corridor or entrance door already carrying CB168 hinges, the CB199 keeps the concealed bearing construction and the heavy duty rating rather than dropping to a ball bearing or plain bearing hinge.
12) Can I substitute a Don-Jo BB74545 for a BEST CB168 on a building entrance door?
They are not interchangeable by rating. The Don-Jo BB74545 is a full mortise ball bearing hinge, 4-1/2 by 4-1/2 steel, square corner, 5 knuckle, and it is rated standard duty. The CB168 is rated heavy duty with concealed bearings. The BB74545 matches the CB168 on size, square corner style and knuckle count, so the door and frame prep lines up, but the duty rating and bearing type are different specifications. On a high-traffic entrance where the spec calls for a heavy weight hinge, the standard duty BB74545 does not meet it.
13) Is a concealed bearing hinge better than a ball bearing hinge for a high traffic commercial door?
They do the same job, they just look different at the barrel. A ball bearing hinge shows the bearing races between the knuckles; the CB168 hides them inside, so the barrel reads as a clean 5-knuckle profile with no visible bearing rings. Functionally the CB168 runs on maintenance-free LifeSpan concealed bearings that need no oil or grease, which is what makes it suited to entrance and corridor doors that cycle all day. If the architect specified a visible ball bearing hinge, the McKinney TCA3386 is a heavy weight 5-knuckle full mortise ball bearing hinge in 4-1/2 x 4-1/2.
14) What is the difference between the BEST CB168 and the CB199 concealed bearing hinge?
Both are full mortise concealed bearing heavy weight hinges in the Architectural Hinges line, so they are close cousins. The practical difference is the model designation your spec or your existing doors call for. If the drawing says CB199, the Stanley Security CB199 is the match; if it says CB168, order the CB168. Sizes are what to check before substituting either way.
15) Will the CB168 hinge rust on an exterior opening?
On the steel CB168 the corrosion answer comes down to the plating: the 651 bright chrome and 652 satin chrome finishes are plated steel, and 641 is a lacquered oxidized bronze finish. In BEST's non-ferrous hinges the pins are stainless steel for corrosion resistance. For a genuinely wet or coastal exterior opening where you want the base metal itself to be corrosion resistant, a stainless hinge is the safer spec, and the Don-Jo BB94545 is a stainless steel full mortise square corner hinge in 4-1/2 x 4-1/2, though it is standard duty rather than heavy.
16) How many CB168 hinges do I need per door?
Standard commercial practice is three hinges for a door up to 7 feet 6 inches, and a fourth added for each additional 30 inches of height. Heavy doors and high-frequency openings, which is what the CB168 is built for, are where skimping to two shows up fastest as sag and a door that stops latching. All three CB168 sizes carry the same finishes, so ordering a matched set of three or four in one finish is straightforward.
17) Which CB168 finish should I order to match the rest of the hardware in my building?
Three finishes are on offer and they map to the standard BHMA codes your other hardware is already marked with: 641 satin bronze light oxidized lacquered, 651 bright chromium plated, and 652 satin chromium plated. 652 is the common commercial default and pairs with the satin chrome locksets and closers most office and institutional buildings run. 651 is the polished look. Check the code stamped on an existing hinge leaf or on your lockset paperwork and match the number rather than the description.
18) What is the difference between the concealed bearing on the CB168 and the plain bearing hinges like the Hager 1279?
The Hager 1279 is a full mortise plain bearing commercial hinge with 5 knuckles, rated medium duty. The CB168 uses concealed bearings and is rated heavy duty. Both are 5 knuckle full mortise hinges, so the door and frame prep is the same family of work. The distinction is the bearing arrangement and the duty rating: a plain bearing hinge has no bearing element between the knuckles, while the CB168 carries maintenance-free LifeSpan concealed bearings intended for high-frequency doors. For a moderate-use interior door the 1279 medium duty plain bearing design is the lighter specification.
19) Will a Hager 1541 work in place of a CB168 on an apartment building corridor door?
The Hager 1541 is a full mortise residential hinge with stainless steel construction, 5 knuckle plain bearing design. The CB168 is specified commercial and heavy duty with concealed bearings. On a shared corridor or entrance door in a multi-family building, the CB168 commercial heavy duty specification is the one written for that traffic; the 1541 is a residential plain bearing hinge, better suited to the unit doors inside the apartment than the corridor opening.
20) My existing hinge is 4-1/2 by 4 inches. Does the CB168 fit that cutout?
The CB168 comes in 4.5 by 4.5 inch, 4.5 by 5 inch and 5 by 5 inch sizes, so a 4-1/2 by 4 inch mortise is narrower in leaf width than any of them and the frame and door prep would need to change. The Don-Jo BB74540 is a full mortise ball bearing hinge at 4-1/2 by 4 inches in satin chrome, which matches that existing cutout directly; it is rated standard duty rather than the heavy duty of the CB168.
21) Do the CB168 hinges need to be oiled or greased once they are in?
No maintenance. The LifeSpan concealed bearings are sealed and take no oil or grease for the life of the door, which is the point of specifying them on a corridor or entrance door that cycles hundreds of times a day. For a property manager standardizing across a building, that removes hinges from the PM schedule entirely.
