BEST BEST-F191-626-3.5x3.5 – Frequently Asked Questions

1) What size BEST F191 hinge do I need for a 1-3/4 inch commercial door?
The F191 comes in 3.5 x 3.5, 4 x 4, 4.5 x 4 and 4.5 x 4.5 inch sizes. A 1-3/4 inch door is standard commercial thickness and normally takes a 4-1/2 inch hinge, so the 4.5 x 4.5 is the usual pick; the 4.5 x 4 works where the frame rabbet is shallower. The 3.5 x 3.5 and 4 x 4 sizes suit 1-3/8 inch interior doors. Measure the existing hinge leaf height and width before ordering so the new one drops into the existing mortise.
2) Will the BEST F191 fit my existing hinge mortise on a hollow metal frame?
The F191 is a full mortise hinge with template screw hole locations, so the holes land on the standard pattern used for both wood and hollow metal doors and frames. It has square corners, so it drops into a square-cut mortise. If your existing mortise is radius cut (rounded corners, typical of a router-prepped wood door), the square corner leaf will not seat cleanly without recutting the corners.
3) What hinge do I use if the door has to swing fully clear of the opening for a wheelchair?
A standard full mortise hinge such as the BEST F191 leaves the door leaf in the opening when it swings back. Where the clear width has to be recovered, the Hager 1260 is a full mortise swing clear hinge with a 5 knuckle plain bearing design at heavy duty. It shares the F191's plain bearing action and 5 knuckle build, but the swing clear geometry carries the door out of the opening rather than parallel to the frame.
4) What is the closest equivalent to a BEST F191 plain bearing hinge from another manufacturer?
The Hager 1279 is the nearest match. Both are full mortise plain bearing commercial hinges with 5 knuckles at medium duty, so the Hager 1279 covers the same medium duty openings the BEST F191 does. The BEST F191 is offered in 3-1/2 x 3-1/2, 4 x 4, 4-1/2 x 4, and 4-1/2 x 4-1/2 sizes across brass, bronze, chrome plated, and stainless finishes, so confirm the size and finish you need matches before treating one as a drop-in for the other.
5) I need to run power through the door for an electric lock - can I use a BEST F191?
No. The BEST F191 is a mechanical plain bearing full mortise hinge with a removable pin and carries no wiring. For a powered opening, the ACSI 5BB1 is a 5 knuckle ball bearing full mortise hinge in 4-1/2 x 4-1/2 with a concealed electric through-wire, 4 wire at 28 gauge. It replaces one hinge in the stack; the remaining hinges on the door can stay conventional.
6) The door has to clear a thick trim or wall projection - the BEST F191 will not let it open far enough. What replaces it?
The BEST F191 comes in 3-1/2 x 3-1/2, 4 x 4, 4-1/2 x 4, and 4-1/2 x 4-1/2, all conventional widths that hold the door close to the frame. For an opening where the door must clear projecting trim or a return wall, use a wide throw hinge: the Hager WTBB1168 is a 4-1/2 x 6 full mortise ball bearing wide throw hinge, heavy weight, with 5 knuckles. The extra leaf width sets the door further off the frame so it can open past the obstruction.
7) Can I replace a BEST F191 hinge without taking the door off?
Yes. The F191 has a removable pin, so you can drive the pin out and separate the leaves with both leaves still screwed to the door and frame. That is the difference between this and a non-removable pin hinge, and it is why maintenance crews specify it on doors that get serviced regularly.
8) Do I need to order the BEST F191 by hand, left or right?
No handing to specify. The F191 is a full mortise hinge with a removable pin, and it is symmetrical, so the same hinge works on a left hand or right hand door. What you do specify is size and finish.
9) What finishes does the BEST F191 hinge come in, and will they match the rest of my building's hardware?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome, 629 bright stainless steel and 630 satin stainless steel. Every one of those is available in all four sizes. If your locksets and exit devices are 626 satin chrome, which is the most common commercial spec, order the hinges in 626 and they carry the same BHMA finish code.
10) Is the BEST F191 hinge suitable for a hospital or healthcare facility?
Yes, and it can be furnished with hospital tips (HT), which are the sloped tips that eliminate the flat ledge on top of the hinge where debris or a gurney strap can catch. Specify HT when ordering. Note the F191 is a plain bearing medium duty hinge, so it belongs on doors without closers; patient room and corridor doors with closers should get a bearing hinge instead.
11) Which material should I pick for the BEST F191, brass, bronze or stainless steel?
The F191 is offered in brass, bronze or stainless steel, and the finish code tells you which you are getting. 629 and 630 are stainless steel, which is what to use on exterior openings, pool and locker areas, kitchens and anywhere with washdown or coastal exposure. 605, 606, 612 and 613 are the brass and bronze finishes, best kept to interior openings where appearance drives the choice. If you need stainless in a bearing hinge instead, the Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge.
12) Can I standardize a facility on the BEST F191 or do I need a heavier hinge on some doors?
The BEST F191 is a medium duty commercial plain bearing hinge, which covers interior and moderate traffic openings across offices, schools, healthcare, retail, and multi-tenant residential. For the doors in the same facility that run heavier - closer-equipped exterior or high traffic leaves - step up within the same architectural family to the Dormakaba CB199 full mortise concealed bearing heavy weight hinge, or to the McKinney TCA3386 heavy weight square corner 5 knuckle hinge in 4-1/2 x 4-1/2. Both keep the full mortise prep, so the door and frame preparation stays consistent across the standard.
13) Is a Don-Jo BB74545 the same thing as a BEST F191 in 4-1/2 x 4-1/2?
They are not the same hinge. The Don-Jo BB74545 is a steel full mortise ball bearing hinge, square corner, 5 knuckle, in 4-1/2 x 4-1/2 at standard duty. The BEST F191 in that size is a plain bearing hinge with square corners and a removable pin, rated medium duty. Both are full mortise 5 knuckle hinges with the same square corner prep, so the frame and door cutout is the same, but the bearing type differs - the ball bearing Don-Jo is the choice where the leaf will see closer load, the plain bearing F191 where it will not.
14) I need a stainless steel hinge in 4-1/2 x 4-1/2 - what are my options besides the BEST F191?
The BEST F191 is available in 629 bright stainless steel and 630 satin stainless steel in 4-1/2 x 4-1/2 as a plain bearing hinge. If you want stainless with a ball bearing instead, the Don-Jo BB94545 is a stainless steel full mortise ball bearing hinge with square corners in 4-1/2 x 4-1/2. For a lighter residential opening, the Hager 1541 is a full mortise plain bearing hinge of stainless steel construction with a 5 knuckle design.
15) What is the difference between the BEST F191 and the Stanley Security CB1960R?
Both are full mortise standard weight hinges in the Architectural Hinges series at medium duty. The difference is the bearing: the BEST F191 uses a plain bearing with a visible 5 knuckle barrel and a removable pin, while the CB1960R uses a concealed bearing, which places the bearing inside the barrel rather than between the knuckles. The F191 is offered in eight finishes from 605 bright brass through 630 satin stainless steel in four sizes up to 4-1/2 x 4-1/2.
16) Which square corner 5 knuckle hinges match the BEST F191 prep in 4-1/2 x 4-1/2?
The BEST F191 has square corners and 5 knuckles, and 4-1/2 x 4-1/2 is one of its four sizes. Peers with the same square corner 5 knuckle full mortise form in 4-1/2 x 4-1/2 include the McKinney TCA2314 and TCA2317, both standard duty, and the Don-Jo BB74545 in steel. Because all are square corner full mortise, the existing mortise in a door already prepped for the F191 takes them without re-routing the corners.
17) Is the Hager 1541 an acceptable substitute for the BEST F191 on a commercial door?
They are not interchangeable by application. The Hager 1541 is a full mortise plain bearing residential hinge with stainless steel construction and a 5 knuckle design. The BEST F191 is specified as a commercial hinge at medium duty, in brass, bronze, or stainless steel with eight finishes. The bearing type and knuckle count line up, but the 1541 is built for residential openings while the F191 is the one carried for commercial traffic in hospitals, schools, hotels, and office buildings.
18) How many BEST F191 hinges do I need per door?
Three per door is the standard commercial count for a door up to 7 feet 6 inches tall, with an extra hinge for every additional 2 feet 6 inches of height. All F191 hinges ship as individual hinges in the size and finish you pick, so order them by the piece and count the openings.
19) Is there a brass ball bearing hinge equivalent to the BEST F191 in brass?
The BEST F191 is available in brass construction with 605 bright brass and 606 satin brass finishes. For a brass hinge with a ball bearing instead of a plain bearing, the Don-Jo BB84545 is a full mortise ball bearing hinge in brass, 4-1/2 x 4-1/2, finished in satin chrome at standard duty. The base metal is the same family; the bearing type and the finish are where the two part ways.
