BEST BEST-F248-652-4 – Frequently Asked Questions

1) Can I use the BEST F248 to replace the 4 inch hinges already on my door without redoing the mortises?
That's what it's built for. The F248 replaces existing 3-1/2 inch (89mm) or 4 inch (102mm) hinges on swing clear openings with minimal modification, and it's offered in matching 3.5" x 3.5" and 4" x 4" sizes. Match the size that's on the door now and the existing frame and door mortises carry over. Note the door has to be square edge for a full mortise hinge; a beveled edge door needs different prep.
2) Is a plain bearing hinge heavy enough for a hospital corridor door, or do I need ball bearing?
The F248 is a medium duty commercial hinge with plain bearing operation. Plain bearing suits normal-traffic openings: patient room doors, exam rooms, classrooms, offices. Where the door is heavy, has a closer on it, or sees constant high-frequency traffic (a main corridor, an entry, a fire-rated assembly with a heavy slab), specify a ball bearing hinge instead. For swing clear in a heavy duty version, the Hager 1260 is a full mortise swing clear hinge with the same 5-knuckle plain bearing arrangement rated heavy duty.
3) Will square corner hinges fit my frame, or do I need radius corner?
The F248 has square corners, which is the standard prep on hollow metal frames and on doors machined with a router and a chisel. If your existing hinges have rounded corners (typical of factory-machined wood doors cut with a hinge router), the square corner leaf won't seat in that pocket without squaring off the corners with a chisel. Pull one existing hinge and look at the leaf corner before ordering.
4) If the door does not need to swing clear of the opening, what standard hinge replaces the BEST F248?
The Hager 1279 is the straight non-swing-clear counterpart. It is a full mortise commercial hinge with 5 knuckles and plain bearing operation at medium duty, matching the F248 on bearing type, knuckle count and duty level, but with a conventional leaf rather than the offset swing clear geometry. Use the F248 only where the door leaf has to clear the opening for wheelchair passage or a narrow corridor; where clearance is not the issue, the 1279 gives the same medium duty plain bearing performance on a standard mortise prep.
5) Does the BEST F248 support an electrified door - card reader, electric lock, or monitored latch?
The F248 is a mechanical hinge with removable pins and plain bearing operation; it carries no wiring. When power has to cross from frame to door for an electric strike, electrified lock or request-to-exit device, the transfer hinge is the ACSI 5BB1, an Ives-pattern 5 knuckle ball bearing full mortise hinge at 4-1/2 by 4-1/2 with concealed electric through-wire in a 4 wire, 28 gauge configuration. It is a conventional hinge rather than swing clear, so an accessible opening that also needs power transfer typically pairs one electrified hinge with swing clear hinges in the remaining positions.
6) What is the closest swing clear hinge to the BEST F248 from another manufacturer?
The Hager 1260 is the nearest match. Like the BEST F248, it is a full mortise swing clear hinge with a 5-knuckle plain bearing design, so it addresses the same goal of swinging the door clear of the opening. The difference is duty level: the Hager 1260 is a heavy duty hinge, while the F248 is a medium duty hinge with plain bearing operation. If the opening carries a heavy door or high traffic, the 1260 is the swing clear option built for that weight; for standard commercial doors the F248 covers the same clearance function at medium duty.
7) What hinge should I use instead of the BEST F248 on a heavy or high-abuse commercial door?
Step up to a heavy weight hinge. The McKinney TCA3386 is a heavy duty square corner 5 knuckle full mortise hinge in 4-1/2 by 4-1/2, and the Stanley Security CB199 is a heavy weight full mortise concealed bearing hinge in the same Architectural Hinges series the F248 belongs to. Both carry more door weight than the medium duty F248. What you give up is the swing clear offset - if the opening still has to pass a wheelchair or gurney at full width, the Hager 1260 is the heavy duty hinge that keeps the swing clear function.
8) Is the BEST F248 handed, or does one hinge work on both left and right hand doors?
Unlike most swing clear hinges, the F248 uses non-rising pins that are easily seated, with reversible flush tips. Flip the tips and the same hinge serves either orientation, so you're not stocking a left and a right for a building with doors swinging both ways. The pin is removable, which also means you can pull the door without unscrewing the leaves once it's hung.
9) What sizes and finishes does the BEST F248 swing clear hinge come in?
Two sizes, 3.5" x 3.5" and 4" x 4", each available in 605 bright brass, 606 satin brass, and 626 satin chrome. Every finish is offered in both sizes, so a property manager standardizing a floor can hold one finish across mixed 3-1/2 and 4 inch openings. The finish numbers are the BHMA codes, so 626 satin chrome matches 626 lever trim and closers already on the doors.
10) What's the difference between the BEST F248 and a standard full mortise hinge like the Don-Jo BB74545?
Geometry, not grade. The Don-Jo BB74545 is a conventional 4-1/2" x 4-1/2" steel square corner 5-knuckle full mortise ball bearing hinge, standard duty, and it hangs the door in the normal position. The F248 is a swing clear: the leaf is offset so the door clears the opening at 95 degrees. If nobody is measuring clear width, the conventional hinge is the simpler part and the usual choice. If the opening has to pass an accessible clear-width dimension, only the swing clear geometry gets you there.
11) My door hits the wall trim when it opens past 90 degrees. Will a swing clear hinge make that worse?
Yes, and it's worth checking before you buy. The F248 throws the door out of the opening, which means the leading edge travels further from the frame than it does on a conventional hinge, and the door needs room to reach 95 degrees to give you the clearance it's designed for. If a return wall, base trim, or an adjacent door blocks the swing short of that, you won't get the clear width and you're better off with a conventional hinge plus a wall stop, or relocating the stop.
12) Is the BEST F248 steel hinge OK for an exterior or wet location?
Keep it inside. The F248 is plated steel, offered in bright brass, satin brass, and satin chrome plated finishes over a steel base, which is fine for interior corridors, patient rooms, and classrooms but will corrode at an exterior or high-humidity opening. Where you need a hinge that tolerates moisture, go stainless: the Don-Jo BB94545 is a 4-1/2" x 4-1/2" stainless steel square corner full mortise hinge. That one is conventional geometry, not swing clear.
13) Which hinge do I use if the door needs to clear trim or a deep frame instead of clearing the opening?
That is a wide throw hinge, not a swing clear hinge. 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 swings the door away from projecting trim or a deep reveal. The BEST F248 solves a different problem: its offset carries the door completely out of the opening at 95 degrees to preserve clear width for accessibility. Openings that need both conditions handled should be confirmed against the frame detail before ordering either.
14) Can the BEST F248 be used on a residential door, or is there a lighter option?
The F248 is specified as a commercial hinge at medium duty, built for healthcare, education and office openings. For residential work, the Hager 1541 is a full mortise plain bearing residential hinge with stainless steel construction and a 5 knuckle design - the same plain bearing operation and knuckle count in a residential-rated product. The 1541 is a conventional hinge, so if the residential opening was specified for accessibility clear width, the swing clear geometry of the F248 is still the reason to choose it.
15) What is the 5-knuckle design on the F248 and does it matter for install?
Five knuckles means the barrel is split into five segments, three on one leaf and two on the other, which is the standard commercial arrangement and spreads the door load across more of the pin. For install it matters in one practical way: a 5-knuckle hinge only mates with another 5-knuckle hinge if you're ever swapping one out mid-door. It also sets the pin at the standard length, so the removable non-rising pin drops in and seats without a special tool.
16) What is the difference between the Don-Jo BB74540 and the BEST F248 for a satin chrome opening?
Both are available in satin chrome - the F248 in 626 satin chrome in 3-1/2 by 3-1/2 and 4 by 4, and the Don-Jo BB74540 as a 4-1/2 by 4 full mortise ball bearing hinge in satin chrome at standard duty. The BB74540 is a conventional ball bearing hinge in an asymmetric 4-1/2 by 4 size, so it suits a frame already prepped for that leaf. The F248 uses plain bearings and the swing clear offset, and its square corners and 5-knuckle build match the standard commercial mortise prep in its two sizes.
