BEST BEST-FBB258NRP-652-4.5 – Frequently Asked Questions

1) What does a swing clear hinge actually do, and when do I need one instead of a standard full mortise hinge?
A swing clear hinge carries the door completely out of the opening when it is swung to 90 degrees, so the door leaf and its thickness no longer eat into the clear width. That is the reason to spec the BEST FBB258NRP over a standard butt hinge: on a narrow corridor door or a patient room door, a standard hinge leaves the door face in the opening and costs you clear width for gurneys, wheelchairs, and carts. If you do not need to recover that width, a conventional full mortise ball bearing hinge is the cheaper and more common choice.
2) Will the BEST FBB258NRP hold up on a heavy commercial door?
It is a standard weight, medium duty hinge, built in steel with two permanently lubricated ball bearings. That suits normal-weight commercial doors in offices, schools, retail, and multi-tenant residential. For a heavy or oversized leaf, or a high-frequency entrance, step up to a heavy weight hinge such as the McKinney TCA3386 in 4-1/2 by 4-1/2 or the Dormakaba CB199 full mortise concealed bearing heavy weight hinge.
3) What size and finish does this BEST swing clear hinge come in?
One configuration: 4-1/2 by 4-1/2 inches with square corners, finished 652 satin chrome over steel. 4-1/2 by 4-1/2 is the standard leaf size for a 1-3/4 inch commercial door, and square corner suits a hollow metal frame with square-corner hinge pockets. If your existing doors are prepped with radius corners, this will not drop into that pocket without rework.
4) Is this hinge a match for the Hager 1260 swing clear hinge?
Both are full mortise swing clear hinges with a 5-knuckle design, but the bearing and the weight class differ. The Hager 1260 is a heavy duty hinge with a plain bearing; the BEST FBB258NRP is medium duty with ball bearings. Ball bearings are what you want on any door with a closer on it or steady traffic, since a plain bearing wears faster under that load. Pick the 1260 if the leaf weight is the deciding factor, the FBB258NRP if bearing life is.
5) I need a monitored or electrified hinge in place of the BEST FBB258NRP - what is available?
The FBB258NRP is a mechanical swing clear hinge with no wire path. To carry power or signal through the opening, the ACSI 5BB1 is a 5-knuckle ball bearing full mortise hinge, 4-1/2 inch by 4-1/2 inch, with a concealed electric through-wire in a 4 wire 28ga configuration. It is a conventional hinge profile, so if the door also needs swing clear geometry the two requirements have to be resolved separately.
6) Can a standard Don-Jo BB74545 hinge replace a BEST FBB258NRP?
Not if the opening needs the clearance. The Don-Jo BB74545 is a 4-1/2 inch by 4-1/2 inch steel full mortise ball bearing hinge with square corners and 5 knuckles, so it matches the FBB258NRP on size, corner style, knuckle count and bearing type, but it is a conventional hinge leaf. The FBB258NRP is a swing clear hinge, which carries the door completely clear of the opening at 90 degrees to recover the door thickness in the clear width. The FBB258NRP also uses a non-removable pin. Use the BB74545 only where clearance and pin security are not requirements.
7) Why a non-removable pin, and does it limit where I can use the hinge?
The NRP pin cannot be driven out once the hinge is installed, so nobody can pull the pin and lift the door off from the outside. That is the standard requirement on any out-swinging door where the hinge barrel is exposed on the unsecure side. The trade-off is service: to take the door down you unscrew the leaves rather than tapping the pin, so allow for that on a door you expect to remove often.
8) Can I get this swing clear hinge with hospital tips for a healthcare job?
Hospital tips are an available option on the FBB258NRP. HT tips are the angled tips that eliminate the flat ledge on the barrel end, which is what infection-control and behavioral-health specs call for so nothing can be hung or caught on the hinge. Combined with the swing clear geometry, that is the usual pairing for patient room and corridor doors.
9) I need to standardize hinges across a building but only a few doors need swing clear. What else should I order?
Use swing clear only where you are recovering clear width, and a conventional ball bearing full mortise hinge everywhere else. In the same 4-1/2 by 4-1/2 square corner size, the Don-Jo BB74545 is the steel standard duty version, BB94545 the stainless steel one for wet or coastal areas, and BB84545 the brass one in satin chrome to match a 652 finish visually. The McKinney TCA2314 and TCA2317 are also square corner 5-knuckle hinges in that size. Keeping one leaf size and one corner style across the building means one door and frame prep everywhere.
10) How many hinges do I need per door, and do I have to worry about handing?
Full mortise butt hinges like the FBB258NRP are non-handed, so one part number covers left and right hand doors. Quantity is by door height: three hinges on a standard 7 foot leaf, four on a taller or heavier leaf. Hinges are sold and installed as leaf pairs per door, so order to the count for the opening rather than one per door.
11) Will a swing clear hinge change the door prep or the frame prep?
The door and frame hinge pockets stay the same as conventional full mortise prep, which is why swing clear hinges retrofit into existing hollow metal frames. What changes is the leaf geometry: the offset carries the door out past the frame stop, so check that nothing on the hinge side, wall returns, adjacent trim, or a wall-mounted device, sits where the door will now travel. BEST publishes templates, a hinge size chart, and an installation guide for marking and drilling before you commit the prep.
12) Which hinge should I use instead of the BEST FBB258NRP if the door has to clear deep trim or swing back against a wall?
A swing clear hinge like the FBB258NRP removes the door from the opening, but it does not gain offset from the frame face. For extra throw, the Hager WTBB1168 is a 4-1/2 inch by 6 inch full mortise ball bearing wide throw hinge with 5 knuckles, rated heavy weight. The wide throw leaf pushes the door further off the jamb to clear projecting trim. Note it does not provide the swing clear profile, so if you need both conditions addressed, verify the opening against the hinge size chart first.
13) What is the heavy weight equivalent to a 4-1/2 by 4-1/2 square corner hinge like the BEST FBB258NRP?
For the same 4-1/2 inch by 4-1/2 inch square corner footprint in a heavier class, the McKinney TCA3386 is a square corner 5 knuckle full mortise hinge at that size, rated heavy duty. The McKinney TCA2314 and TCA2317 are standard duty in the same size and corner style. None of the three is a swing clear hinge, so they suit a conventional jamb condition rather than one where the FBB258NRP is recovering clear opening width.
14) Does the Don-Jo BB74540 fit the same prep as the BEST FBB258NRP?
No. The Don-Jo BB74540 is a 4-1/2 inch by 4 inch full mortise ball bearing hinge in satin chrome, standard duty. The FBB258NRP variant is 4-1/2 inch by 4-1/2 inch, so the leaf widths differ by half an inch and the frame and door mortise will not line up one for one. If you are matching an existing prep, confirm the leaf dimensions against the hinge size chart before ordering.
15) Is the Hager 1541 an acceptable lower-cost option in place of the BEST FBB258NRP?
Not for a commercial opening. The Hager 1541 is a full mortise plain bearing residential hinge in stainless steel with a 5 knuckle design. The FBB258NRP is specified for commercial use with ball bearings and a non-removable pin, and it is used in offices, schools, healthcare and multi-tenant buildings. Where the door has a closer or sees daily commercial traffic, the plain bearing residential hinge is not the same class of product.
