BEST BEST-1900R-652-4.5x4.5 – Frequently Asked Questions

1) Does the BEST 1900R hinge need to be ordered by hand, left or right?
No handing to specify. The flush tips and pin are reversible and the pin is non-rising and removable, so one hinge covers either swing. That makes it a simple stocking item for a maintenance shop working both handings.
2) Can the 1900R be used on both hollow metal frames and wood doors?
Yes. The screw hole locations are to template, which is what lets the same hinge go into a wood door or a hollow metal door and frame. It's a full mortise hinge, so both leaves get mortised flush into the door edge and the frame rabbet.
3) Do I need square corner or radius corner hinges for my existing door prep?
The 1900R is a square corner hinge, which is the standard prep on hollow metal frames and factory-machined commercial doors. If your existing mortises are rounded, a square corner hinge will leave a gap at the corners and you want a radius corner hinge instead. Check one existing hinge pocket before you order a building's worth.
4) I need the door to swing fully clear of the opening for wheelchair access. Is this the right hinge?
No. The 1900R is a conventional full mortise hinge, so the open door leaf still sits in the clear opening and eats a couple of inches of width. For that you want a swing clear hinge such as the Hager 1260 full mortise swing clear hinge. Wide throw is a different problem again, clearing trim or a deep reveal, and the Hager WTBB1168 4-1/2 by 6 inch wide throw hinge handles that.
5) What should I use instead of the BEST 1900R on a door with a closer or high traffic?
The 1900R is a standard weight, medium duty hinge described for interior or exterior doors without door closers. For an opening with a closer or heavier door, step up to a heavy weight hinge such as the Stanley Security CB199 full mortise concealed bearing heavy weight hinge, which keeps the concealed bearing style, or the McKinney TCA3386 square corner 5 knuckle full mortise hinge in 4-1/2 by 4-1/2 heavy weight if you prefer a ball bearing five knuckle.
6) What is the closest concealed bearing equivalent to the BEST 1900R hinge?
The Stanley Security CB1960R is the nearest match. Like the BEST 1900R it is a full mortise concealed bearing standard weight hinge in the Architectural Hinges series, and both are rated medium duty. If you are matching concealed bearing hardware already hung on other openings, the CB1960R keeps the same bearing style and weight class.
7) The BEST 1900R will not work because I need power transfer to the door. What hinge should I order?
The BEST 1900R is a mechanical concealed bearing hinge with a removable pin and no provision for wiring. For an electrified opening use the ACSI 5BB1 5-knuckle ball bearing full mortise hinge, 4-1/2 by 4-1/2, with concealed electric through-wire (4 wire, 28ga), which carries current from frame to door for electric locks or monitoring.
8) What do I use instead of the BEST 1900R if the door has to swing fully clear of the opening for ADA clearance?
A standard full mortise hinge like the BEST 1900R leaves the door leaf in the clear opening when open. Where you need the full width, use the Hager 1260 full mortise swing clear hinge, a heavy duty 5-knuckle plain bearing design that carries the door out of the opening. That is the usual choice on healthcare corridors and gurney routes.
9) My door needs to clear a deep trim or brick mold. Is the BEST 1900R the right hinge?
No. The BEST 1900R is a standard 4-1/2 by 4-1/2 full mortise hinge, so the leaf width is not enough to throw the door past projecting trim. Use a wide throw hinge such as the Hager WTBB1168, a 4-1/2 by 6 inch full mortise ball bearing wide throw hinge, heavy weight with 5 knuckles, which gives the extra leaf width to swing the door clear.
10) What is the difference between a concealed bearing hinge and a ball bearing hinge?
Concealed bearing hinges hide the bearings inside the knuckles, so the barrel looks like a plain hinge but still turns on bearings. A 5 knuckle ball bearing hinge shows the bearing races between knuckles. The 1900R is concealed bearing with 3 knuckles and square corners, so it reads cleaner on exposed architectural openings. If you want the conventional ball bearing look, the Don-Jo BB74545 is a 4-1/2 by 4-1/2 steel, square corner, 5 knuckle ball bearing hinge.
11) How do you remove the pin on the BEST 1900R to take a door down?
The pin is removable and non-rising, with a hole in the bottom tip. Drive a pin punch or nail up through that hole to push the pin out, and the leaves separate without unscrewing either leaf. That's the feature that lets a maintenance tech pull a door for painting or carpet and rehang it alone.
12) Are the 1900R hinges okay for exterior doors in a school or apartment building?
Yes, within their duty level. They're rated commercial, medium duty, and the description calls out interior or exterior doors in hospitals, churches, schools, airports, hotels, malls, apartment houses and office buildings, provided the door has no closer. Steel construction, so on a coastal or wash-down opening a stainless hinge like the Don-Jo BB94545 makes more sense for corrosion.
13) Do I need a bearing hinge at all, or will a plain bearing hinge do?
Plain bearing hinges are fine on light interior doors with low traffic. Once the door is heavier or the opening cycles all day, bearings cut the friction and the squeak, which is what the 1900R's concealed bearings are for. If you want a plain bearing option, the Hager 1279 is a medium duty full mortise plain bearing commercial hinge with 5 knuckles, and the Hager 1541 is the residential stainless plain bearing version.
14) I need a hinge in satin chrome but not in steel. What are my options versus the BEST 1900R?
The BEST 1900R is supplied in 652 satin chrome over steel at 4-1/2 by 4-1/2. If you need a different base metal in the same size, the Don-Jo BB84545 is a brass full mortise ball bearing hinge 4-1/2 by 4-1/2 in satin chrome, and the Don-Jo BB94545 is a stainless steel square corner full mortise ball bearing hinge in the same size. Both are 5-knuckle ball bearing rather than 3-knuckle concealed bearing.
15) Can I substitute the Don-Jo BB74540 for the BEST 1900R?
Not on the same prep. The BEST 1900R is 4-1/2 by 4-1/2, while the Don-Jo BB74540 is a 4-1/2 by 4 inch full mortise ball bearing hinge in satin chrome. The shorter leaf width means the frame and door mortise depth will not match a 4-1/2 by 4-1/2 cutout. Match the finish if you like, but confirm the leaf dimension against the existing mortise first.
16) How many 1900R hinges do I need per door?
Standard practice is three hinges on a door up to 7 feet 6 inches tall, and a fourth for anything taller. Since the 1900R is medium duty and not intended for closered doors, don't try to make up for a heavy leaf by adding hinges, step up to a heavy weight hinge instead.
17) How do the McKinney TCA2314 and TCA2317 compare to the BEST 1900R?
All three are 4-1/2 by 4-1/2 square corner full mortise hinges. The McKinney TCA2314 and TCA2317 are 5 knuckle standard duty hinges, while the BEST 1900R is a 3 knuckle concealed bearing hinge rated medium duty. If your hardware schedule calls out a five knuckle barrel, the McKinney pair matches that look; the 1900R gives the flush concealed bearing barrel.
