Stanley Security BB855 5X6 P – Frequently Asked Questions
1) What does "no holes, not swaged" mean on the Stanley BB855 prison hinge, and what does that mean for installation?
It means the hinge leaves arrive blank, with no screw or bolt holes drilled and no offset pressed into the leaf at the barrel. The installer or the door/frame fabricator drills and preps to match the detention door and frame, which is how most correctional openings are done because the through-bolt pattern is set by the door manufacturer, not the hinge. Stanley calls this Application A. The BB855 can also be ordered with hole templates, or in mortised, half-mortised, swaged or non-swaged forms if your opening needs a specific prep.
2) Which heavy duty ball bearing hinge should I use on a standard commercial door instead of the BB855?
For a conventional heavy commercial opening rather than a detention door, the Ives 3CB1HW steel heavy weight concealed bearing full mortise hinge is the closer fit, as is the Hager BB1168 full mortise ball bearing heavy duty hinge with a non-removable pin. The Stanley BB855 is a double weight prison hinge furnished with no holes and not swaged, which means the installer preps the leaf; the Ives and Hager units are conventional full mortise hinges.
3) I need to run power or monitor door position through the hinge - does the BB855 do that?
The Stanley BB855 is a mechanical double weight prison hinge with a welded pin and no wiring provision. For power transfer, the Command Access ETH-BB68 is a heavy duty 5 knuckle steel energy transfer hinge, and the BEST CECB179-12C is a steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If you also need door position sensing, the Command Access ETM-BB68 adds an integrated door position switch on a heavy duty 5 knuckle base.
4) If the concern is pin removal from the secure side rather than door weight, what else should I look at?
The Hager BB1168 is a full mortise ball bearing heavy duty hinge supplied with a non-removable pin, the Deltana CSB45N is a 4-1/2 inch by 4-1/2 inch square hinge pair with a non-removable pin, and the Deltana DE44R5TA is a 4 inch by 4 inch steel security hinge pair with a 5/8 inch radius. The Stanley BB855 addresses this with a welded pin rather than a set screw, alongside its double weight steel leaves.
5) Does the Stanley BB855 come in a plated finish, or does it have to be painted?
It ships in USP / 600, primed for painting. That is a paintable prime coat, not a decorative plating, so the finish coat is applied on site or in the shop to match the facility's color scheme. One finish is offered on this hinge. If you need a plated commercial finish out of the box, satin chrome heavy weight hinges like the Don-Jo HWBB85045 in 5 x 4-1/2 are the direction to look.
6) What is the difference between the Stanley BB855 and the BEST BB855 prison hinge?
They are the same designation carried under two brands. BEST lists its BB855 as a heavy-duty steel double weight concealed ball bearing prison hinge in the Detention Hardware series, which matches the Stanley BB855 double weight concealed ball bearing construction. If a facility is already standardized on one brand's detention hardware, order to match that brand for the paperwork; functionally you are looking at the same hinge type.
7) Can I use a Don-Jo heavy weight ball bearing hinge in place of the Stanley BB855?
The Don-Jo HWBB75045 is a heavy weight full mortise ball bearing hinge in steel at 5 inches by 4-1/2 inches with a satin chrome finish, and the HWBB85045 is a 5 inch by 4-1/2 inch brass version. Both are heavy duty and pre-drilled full mortise hinges, so they serve standard heavy commercial doors rather than detention openings. The Stanley BB855 is a double weight prison hinge at 5 inches by 6 inches, primed for painting, so the leaf width and the prep differ.
8) Does a residential ball bearing hinge like the Emtek 94013 substitute for the BB855?
No. The Emtek 94013 is a heavy duty ball bearing hinge pair at 3-1/2 inches by 3-1/2 inches in plated steel with square corners, sized for residential and light interior doors. The Stanley BB855 is a commercial double weight steel prison hinge at 5 inches by 6 inches with a concealed ball bearing and welded knuckles. The names both say ball bearing, but the leaf size and load class are not in the same category.
9) What is the difference between the Stanley BB855 and a pivot for a very heavy door?
The BEST CB1969R is a concealed bearing heavy weight pivot-reinforced hinge, and the BEST DAP-3 is a heavy duty double acting pivot for commercial interior doors in the Emergency Rescue Hardware series. Pivots carry the door on the top and bottom of the leaf rather than along the hinge edge, which changes the frame and floor prep. The Stanley BB855 is a hinge that mounts along the door edge and is furnished with no holes and not swaged.
10) Is a half mortise hinge an alternative when the frame will not take a full mortise prep?
The Hager 1129 is a half mortise plain bearing commercial hinge, 4-1/2 inch standard weight steel with a heavy duty rating, which mortises into the door and surface-mounts to the frame. The Stanley BB855 double weight prison hinge is designed for full surface use in heavy applications and can also be ordered in mortised or half-mortised forms depending on the application, so confirm the form when you order.
11) Are the corners on the Stanley BB855 square or radiused?
Square corners. Since the hinge is furnished with no holes and not swaged for full-surface heavy applications, the square leaf sits flat against the door face and frame rather than dropping into a radiused router pocket. Radiused corners belong to hinges that mortise into a machine-routed prep.
12) Is this hinge suitable for a high-traffic commercial opening, or is it strictly for jails?
Rated commercial and heavy duty, and the concealed ball bearing with hardened races and well-lubricated balls is built for constant cycling. Correctional facilities are the primary use, but the same construction suits X-ray and lead-lined doors and any oversized, heavy steel leaf where a standard hinge sags. The steel substrate and primed finish mean it gets painted to blend with the opening.
13) Which hinge should I standardize on for ordinary office doors in the same facility where BB855 hinges are used on the secure doors?
For the standard openings, the McKinney MP79 MacPro full mortise 5-knuckle hinge and the MPB79 MacPro 5-knuckle hinge are standard duty commercial units, and the Orca 3535 Series 4-1/2 inch by 4-1/2 inch square corner ball bearing commercial hinge is a medium duty square corner option that matches the square corner style of the Stanley BB855. Keep the double weight BB855 on the heavy and secure leaves.
