BEST BEST-CB179NRP-652-4.5x4.5 – Frequently Asked Questions

1) What does the non-removable pin on the CB179NRP actually protect against?
The NRP suffix means the pin cannot be pulled out of the barrel, so a door cannot be taken off its hinges from the outside. That matters on out-swinging doors, where the hinge barrel sits on the unsecured side: exterior service doors, stairwell and tenant entries, storage rooms. On an in-swinging door the barrel is already inside, so NRP buys you less.
2) Is the BEST CB179NRP heavy enough for a high-traffic commercial door?
It is a medium duty, commercial-rated standard weight hinge with concealed bearings and a 5-knuckle barrel. That suits interior office, classroom, patient room, and retail back-of-house doors of normal weight and normal frequency. For a heavy or high-frequency opening, a heavy weight hinge is the right call: the Stanley Security CB199 is the heavy duty concealed bearing version in the same Architectural Hinges family, and the McKinney TCA3386 is a heavy weight 5-knuckle full mortise in the same 4-1/2 by 4-1/2 size.
3) Will the CB179NRP drop into my existing 4-1/2 inch square corner hinge pockets?
The CB179NRP is a full mortise hinge with square corners in 4-1/2 x 4-1/2 inch, so it matches a standard square-corner mortise already cut for that size. If your existing pockets are radius-cut, round corner versions are available under an RD prefix with a 1/4 inch (6.4mm) radius on all sizes. Confirm the corner style in the pocket before you order, since a square leaf will not seat in a radiused mortise without rework.
4) Can I use the CB179NRP on an aluminum storefront door?
Yes. It is made for aluminum doors in aluminum frames in slip-in applications, where one leaf inserts through a slot in the door or the frame. That is the typical glass front and storefront condition. For a hollow metal or wood door you are cutting a conventional mortise instead, which this hinge also handles as a full mortise unit.
5) I need to run power through the door for an electrified lock. Can the CB179NRP do that?
The CB179NRP is a mechanical hinge with no through-wire provision. For an electrified opening, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge at 4-1/2 by 4-1/2 inches with a concealed electric through-wire, 4 wire at 28 gauge. It matches the CB179NRP's mortise size and 5 knuckle count, so the door and frame prep carries over, but it is a ball bearing hinge rather than concealed bearing.
6) The CB179NRP is medium duty. What should be used on a heavy traffic or high frequency opening instead?
For heavier openings, the Dormakaba CB199 is a full mortise concealed bearing heavy weight hinge in the same Architectural Hinges series, rated heavy duty rather than the CB179NRP's medium duty. The McKinney TCA3386 is another heavy weight option, a square corner 5 knuckle full mortise hinge at 4-1/2 by 4-1/2 inches, matching the CB179NRP's square corner and 5 knuckle configuration in that size.
7) Is a ball bearing hinge like the Don-Jo BB74545 the same thing as the BEST CB179NRP?
They are both 4-1/2 by 4-1/2 inch steel square corner 5 knuckle full mortise hinges, but the bearing construction differs. The CB179NRP uses a concealed bearing, where the bearing is hidden within the knuckles, and carries a non-removable pin. The Don-Jo BB74545 is a ball bearing hinge with visible bearing races between knuckles and is rated standard duty. If the specification calls out concealed bearing for appearance or for a security pin, the ball bearing hinge is not a drop-in match.
8) I need the door to swing clear of the opening for ADA clearance. Will the CB179NRP do that?
No. The CB179NRP is a conventional full mortise hinge, so the door leaf remains in the opening when swung. For clear opening width, the Hager 1260 is a full mortise swing clear hinge with a 5 knuckle plain bearing design, rated heavy duty. That is a different hinge geometry, not a finish or weight variation on the CB179NRP.
9) The door has to clear deep trim and swing back 180 degrees. Is there an alternative to the CB179NRP?
For that condition you need a wide throw hinge rather than the 4-1/2 by 4-1/2 inch CB179NRP. The Hager WTBB1168 is a 4-1/2 by 6 inch full mortise ball bearing wide throw hinge, heavy weight with 5 knuckles. The extra leaf width carries the door past the trim; the CB179NRP's square leaf will not.
10) My existing frame is prepped 4-1/2 by 4 inches. Does the CB179NRP fit?
The CB179NRP is offered at 4-1/2 by 4-1/2 inches, so it will not drop into a 4-1/2 by 4 inch prep without reworking the frame. The Don-Jo BB74540 is a full mortise ball bearing hinge at 4-1/2 by 4 inches in satin chrome, which matches that narrower prep and the satin chrome finish the CB179NRP also offers.
11) What size and finishes does the BEST CB179NRP full mortise hinge come in?
The CB179NRP is offered in a 4-1/2 x 4-1/2 inch size, in three finishes: 600 primed for painting, 641 oxidized bronze, and 652 satin chrome over steel. The 600 is the one to order if the openings are being painted out to match frames; 652 is the usual choice for standardizing on chrome lever and closer hardware.
12) Concealed bearing or ball bearing hinge, what is the difference for a commercial door?
Both carry the load on bearings rather than metal on metal. On the CB179NRP the bearings sit inside the barrel, so the knuckles read as an even, unbroken barrel and the door swings quietly, which is why they get specified in hospitals, hotels, and offices where visible bearing races are unwanted. An exposed ball bearing hinge like the Don-Jo BB74545 or the McKinney TCA2314, both 4-1/2 x 4-1/2 five-knuckle full mortise, does the same job with the races visible between knuckles.
13) Do I need to specify handing when ordering the CB179NRP?
No handing call is needed. A standard full mortise butt hinge with a five-knuckle barrel is symmetrical and works left or right hand. What you do need to settle is finish, corner style (square as standard, RD for round), and whether the opening actually warrants the NRP pin.
14) Does a wheelchair-accessible door need a different hinge than the CB179NRP?
Yes, if you are trying to recover clear opening width. A standard full mortise hinge like the CB179NRP leaves the door edge in the opening when swung. To gain the extra inches for a clear passage, use a swing clear hinge such as the Hager 1260 full mortise swing clear, which pulls the leaf fully out of the opening. For a door that must clear trim or a thick wall return, a wide throw hinge like the Hager WTBB1168 at 4-1/2 x 6 inches is the answer.
15) Are the CB179NRP hinges steel or stainless, and will they hold up outdoors?
Construction is steel, with the 652 option satin chrome plated over that steel and the 600 supplied primed so you can paint it. Steel with a plated or painted finish is a dry interior or protected exterior proposition. For a coastal, pool, or washdown location, go stainless: the Don-Jo BB94545 is a stainless steel full mortise square corner hinge in 4-1/2 x 4-1/2, and the BB84545 is the brass equivalent in satin chrome.
16) Is the Hager 1279 a substitute for the BEST CB179NRP?
The Hager 1279 is a full mortise commercial hinge with 5 knuckles at the same medium duty level as the CB179NRP, so it sits in the same weight class. The difference is bearing type: the 1279 is a plain bearing hinge, while the CB179NRP runs on a concealed bearing and adds a non-removable pin. Plain bearing hinges suit lower frequency openings; use the CB179NRP where the concealed bearing and pin security were specified.
17) Can I use the Hager 1541 in place of the CB179NRP on an apartment corridor door?
The Hager 1541 is a full mortise residential hinge in stainless steel with a 5 knuckle plain bearing design. The CB179NRP is specified for commercial use at medium duty with a concealed bearing and non-removable pin. For a corridor door in a multi-tenant building, the CB179NRP is the commercial-rated choice; the 1541 is built for residential openings.
18) Where do I get the mortise template and install instructions for the BEST CB179NRP?
BEST publishes hinge installation instructions and general hinge information sheets alongside a 5-knuckle concealed bearing document covering the family, and all three are available as downloadable PDFs with the product. Pull the installation sheet before cutting so the pocket depth and screw pattern are right the first time, and use the manufacturer template to lay out hole locations on both door and frame.
19) What is the difference between the McKinney TCA2314 and TCA2317 as alternatives to the CB179NRP?
Both the McKinney TCA2314 and TCA2317 are square corner 5 knuckle full mortise hinges at 4-1/2 by 4-1/2 inches rated standard duty, so either matches the CB179NRP's size, corner style and knuckle count for door and frame prep. They differ from each other by model designation within McKinney's line. Against the CB179NRP, neither carries the non-removable pin designation.
20) Is there a brass-bodied alternative to the steel CB179NRP in the same size?
Yes. The Don-Jo BB84545 is a full mortise ball bearing hinge at 4-1/2 by 4-1/2 inches in brass with a satin chrome finish, rated standard duty. The CB179NRP is steel with a concealed bearing at medium duty and also offers a satin chromium plated 652 finish, so the two can match visually while differing in base material and bearing type.
