BEST F179-652-3.5x3.5 – Frequently Asked Questions

1) Will the BEST F179 hinge work on a door with a closer on it?
No. The F179 is a plain bearing hinge rated medium duty, which suits average frequency commercial doors without closers. Put a closer on a door and the constant cycling wears a plain bearing knuckle. For that opening go to a ball bearing or concealed bearing hinge: the Stanley Security CB1960R is the concealed bearing standard weight equivalent in the same Architectural Hinges series, and the Don-Jo BB74545 is a 4-1/2 x 4-1/2 steel square corner 5-knuckle ball bearing option.
2) What size BEST F179 hinge do I need for a 1-3/4 inch commercial door?
The F179 comes in 3.5 x 3.5, 4 x 4, 4.5 x 4, 4.5 x 4.5, 4.5 x 5 and 5 x 5 inch. For a standard 1-3/4 inch commercial door the usual call is 4-1/2 x 4-1/2. The 3.5 x 3.5 and 4 x 4 sizes are for lighter 1-3/8 inch interior doors. Hinge height goes up with door weight and width, and the wider leaf sizes (4.5 x 5, 5 x 5) give you clearance for thicker doors or trim projection.
3) Does the BEST F179 hinge fit both wood and hollow metal doors?
Yes, it uses template screw hole locations, so the hole pattern lands where a standard hollow metal frame is already prepped and matches wood door and frame mortises cut to template. That is what lets one hinge cover both wood and hollow metal openings in the same building.
4) Can I take the door down without unscrewing the BEST F179 hinges?
Yes. The F179 has a removable pin, so you drive the pin out and lift the door off the frame leaf with all screws left in place. That is the difference between a ten minute door pull and re-cutting a mortise. Note this also means the pin can be pulled from either side, so on an outswing exterior opening where the barrel is exposed you want a non-removable pin or a security stud hinge instead.
5) Will a full mortise hinge like the BEST F179 work if my door and frame are not routed?
No. Full mortise means both leaves sit in routed pockets, one in the door edge and one in the frame rabbet, flush with the surface. If the opening has never been prepped you have to cut those mortises to template before it will hang. On a frame that is already prepped for a standard 4-1/2 hinge, the F179 drops straight in.
6) Do the BEST F179 square corner hinges fit a frame prepped with radius corners?
No. The F179 has square corners, which matches hollow metal frames and wood doors mortised with a chisel or square corner router template. If your existing hinges have rounded 1/4 or 5/8 inch radius corners, a square corner leaf will not seat in that pocket without squaring it off. Check the corner of the hinge you are pulling out before you order.
7) I need a hinge that carries power to an electric lock. Can the BEST F179 do that?
No. The F179 is a mechanical hinge with no wire path through the barrel. For an electrified opening feeding an electric strike, electrified lever or maglock monitoring, use an electric through-wire hinge: the ACSI 5BB1 is a 4-1/2 x 4-1/2 five knuckle ball bearing full mortise hinge with concealed electric through-wire, 4 wire 28 gauge. Common practice is one electrified hinge in the position closest to the lock and standard hinges like the F179 in the other positions on the same door.
8) My door hits the wall trim when it opens. Will the BEST F179 clear it?
No, a standard full mortise butt hinge like the F179 sets the door on a normal pivot line and does not throw the leaf clear of the frame or trim. For a door that must swing clear of heavy casing, use a wide throw hinge such as the Hager WTBB1168, a 4-1/2 x 6 inch heavy weight ball bearing wide throw. If instead you need the full width of the opening clear for a gurney or wheelchair, that is a swing clear hinge like the Hager 1260.
9) What is the closest equivalent to the BEST F179 hinge from another manufacturer?
The Hager 1279 is the nearest match. Like the BEST F179, it is a full mortise plain bearing hinge with a 5 knuckle design rated medium duty, so it suits the same average frequency commercial openings without a closer. The F179 comes in 3.5 x 3.5, 4 x 4, 4.5 x 4, 4.5 x 4.5, 4.5 x 5 and 5 x 5 sizes with square corners and a removable pin.
10) What hinge do I use for a wet or corrosive area instead of a steel hinge?
Specify a stainless or brass leaf. The Don-Jo BB94545 is a full mortise ball bearing hinge in 4-1/2 x 4-1/2 stainless steel with a square corner, and the Don-Jo BB84545 is the same 4-1/2 x 4-1/2 full mortise ball bearing hinge in brass, satin chrome finish. The BEST F179 is a steel hinge, offered in nine finishes including primed for painting, satin brass, satin bronze, satin nickel and satin chrome.
11) Do I need to specify handing when ordering the BEST F179 hinge?
No. The F179 is a plain full mortise butt hinge with a removable pin and five knuckles, symmetrical top to bottom, so one part works on a left or right hand door. You pick finish and size only. Handing only becomes an order variable on hinges with a non-removable pin, a security stud, or a swing clear geometry like the Hager 1260.
12) What finishes does the BEST F179 hinge come in, and which one do I order to paint it?
Nine finishes: 600 primed for painting, 632 bright brass, 633 satin brass, 639 satin bronze, 640 satin bronze dark, 641 oxidized bronze, 646 satin nickel, 651 bright chrome and 652 satin chrome. If the hinges get painted out with the frame, order 600 primed. For matching existing commercial hardware, 652 satin chrome is the usual match to a US26D / 626 door set, and 646 satin nickel to a brushed nickel package.
13) How is the BEST F179 different from the Hager 1279 hinge?
They are the same class of part. Both are full mortise plain bearing commercial hinges with five knuckles rated medium duty, so either one hangs an average frequency interior commercial door. The F179 carries nine finish options and six sizes from 3.5 x 3.5 to 5 x 5. If you are already standardized on one brand across a facility, matching it is worth more than the difference between them.
14) Is the BEST F179 steel hinge OK on an exterior or damp opening?
The F179 is steel, which is the right call for interior commercial openings such as hospitals, schools and offices. Steel will corrode in a wet, coastal or wash down environment. For those openings go to stainless: the Don-Jo BB94545 is a 4-1/2 x 4-1/2 stainless steel square corner full mortise ball bearing hinge, and the Don-Jo BB84545 is the brass version in satin chrome.
15) How many BEST F179 hinges do I need per door?
Three per leaf is the standard commercial count for a door up to 90 inches tall, with a fourth added on taller doors. Order all of them in the same size and finish so the mortises and the sightline match; the F179 runs from 3.5 x 3.5 through 5 x 5 in nine finishes, and mixing sizes on one door will not seat. On a pair of doors, double the count.
16) Is a ball bearing hinge a drop-in substitute for the F179?
In a 4-1/2 x 4-1/2 square corner opening the prep matches. The Don-Jo BB74545 is a full mortise ball bearing hinge in 4-1/2 x 4-1/2 steel with square corners and 5 knuckles, and the McKinney TCA2314 is a square corner 5 knuckle full mortise hinge at the same 4-1/2 by 4-1/2. The difference is the bearing: the BEST F179 uses plain bearing construction, while those two run on ball bearings, which is the usual choice where a closer or heavier leaf loads the barrel.
17) Can I use the Hager 1541 in place of the BEST F179 on an office door?
They are not the same class of hinge. The Hager 1541 is a full mortise plain bearing residential hinge with stainless steel construction and a 5 knuckle design. The BEST F179 is specified as commercial and medium duty for hospitals, schools, offices and similar facilities, so for a commercial opening the F179 or another commercial rated hinge is the match; the 1541 is built for residential service.
18) What is the difference between the BEST F179 and the Stanley Security CB1960R?
Both are BEST Architectural Hinges series full mortise hinges rated medium duty, so they carry the same class of opening. The CB1960R is a concealed bearing standard weight hinge, where the bearing is hidden inside the barrel; the F179 uses plain bearing construction with 5 knuckles, square corners and a removable pin. Choose by whether the specification calls for a concealed bearing barrel or a plain bearing.
19) Are the McKinney TCA2314 and TCA2317 interchangeable with the F179 across a building standard?
They match on prep and pattern: both the McKinney TCA2314 and TCA2317 are square corner 5 knuckle full mortise hinges at 4-1/2 by 4-1/2, standard duty, which lines up with the BEST F179 in its 4.5 x 4.5 square corner 5 knuckle form. If a facility is standardizing, the practical decision is finish continuity and bearing type across the doors rather than the mortise itself, since the F179 is a plain bearing hinge offered in nine finishes.
