BEST BEST-641-UL-HT-600-6.8 – Frequently Asked Questions

1) What door heights does the BEST 641 continuous hinge cover?
The 641 comes in five lengths: 80, 84, 86, 96 and 120 inches. For standard 7-foot openings the 84 inch length is the usual pick, 96 inches covers an 8-foot door, and 120 inches handles 10-foot tall doors that would otherwise need stacked butt hinges. Continuous hinges are normally ordered slightly shorter than the door height, so measure the actual door leaf before choosing.
2) Can the BEST 641 hinge be used on a 3-hour fire rated door assembly?
Yes. The BEST 641 continuous hinge is fire rated for up to and including 3 hours, so it can be used in fire door assemblies rated at 3 hours or less.
3) Is the BEST 641 a full mortise hinge or does it surface mount?
Full mortise. The leaves attach to the edge of the door and the frame, so the door and frame both have to be routed to accept the leaves, and only the slim hinge bevel shows when the door is closed. If the existing door and frame are not prepped and you do not want to machine them, a surface-mounted option is the better route, such as the ABH A460HD half surface hinge or the Design Hardware full surface geared hinge.
4) Is the NGP HD1100A concealed hinge a substitute for the BEST 641 on a Grade 1 spec?
They are not interchangeable on a Grade 1 submittal. The BEST 641 is certified to ANSI/BHMA A156.26-2006, Grade 1-300. The NGP HD1100A is an 83 inch concealed continuous geared hinge listed at Grade 3. If the spec calls for Grade 1, the Pemko CFM84SLF-HD1 full mortise short leaf flush hinge and the Pemko FM-RG Series are both listed Grade 1 and stay in the full mortise family with the 641.
5) What is the closest full mortise continuous hinge equivalent to the BEST 641?
The BEST 641 is a full mortise continuous hinge, so the nearest like-for-like alternatives are other full mortise geared continuous hinges. Pemko's FM-RG Series is a Grade 1 aluminum full mortise raised geared continuous hinge with a 180-degree swing, and Design Hardware's FMHD is a heavy duty full mortise continuous geared hinge. ABH's A120HD is a heavy duty aluminum continuous gear hinge in a full mortise configuration with Easy Install Technology. All four mount into the edge of the door and frame the same way the 641 does, so the door and frame prep concept is the same; the BEST 641 differs in being a steel hinge supplied with hospital tips, while the Pemko and ABH options are aluminum geared hinges.
6) My opening needs a 3-hour fire rating. Which continuous hinges meet that besides the BEST 641?
The BEST 641 is fire rated for up to and including 3 hours. Among the geared continuous hinges, the NGP HD1100A, HD5400A and HD5700 are each listed as 10C fire rated for 90 minutes on hollow metal, which is a shorter rating than the 641 carries. If the assembly on your drawing calls for a 3-hour hinge, the BEST 641 is the one in this group that states that duration.
7) I need a continuous hinge for a behavioral health room that cannot be barricaded. Does the BEST 641 do that?
The BEST 641 is a conventional full mortise continuous hinge with hospital tips, intended for healthcare and high-traffic commercial openings, but it swings in one direction like a standard hinge. For a room that must not be blocked from inside, the Pemko DSH1000 is a Grade 1 anti-barricade continuous hinge with 100-degree bidirectional operation, which lets the door be pushed the other way. ABH's A135HD is a heavy duty aluminum continuous gear hinge described as a safety design.
8) Why does a hospital or behavioral health job call for hospital tips on a continuous hinge?
Hospital tips are sloped rather than square, so there is no flat ledge at the ends of the hinge for a gown, sheet, IV line or wristband to catch on, and nothing to hang an object from. Hospital tips ship with the 641, so you do not order them separately.
9) What finish does the BEST 641 come in, and can it be painted to match our other doors?
One finish: 600, primed for painting. It arrives ready to take a topcoat, so you paint it to match the door and frame. If you need a mill or clear anodized aluminum look with no field painting, an aluminum geared hinge such as the ABH A120HD full mortise is the different direction to go.
10) Will the BEST 641 keep a sagging door from dropping again?
That is the main reason it gets specified. The load rides the full length of the door edge instead of two or three butt hinges, and there are two stainless steel bearings, top and bottom, that carry the vertical load and also keep dirt from collecting in the pivot area. On a door that has already pulled its butt hinge screws loose, the mortise prep for the 641 usually lands in fresh material.
11) Do I need a template or special prep to install the BEST 641 full mortise hinge?
Yes. Both the door edge and the frame rabbet have to be routed to a full mortise pocket that accepts the leaves, and manufacturer templates are used to lay out the mounting hole locations before machining. Plan on shop or field routing, not a drop-in swap for butt hinges. If the openings are already hung and you cannot machine them, a surface-applied hinge like the Design Hardware full surface offset geared hinge avoids the mortise work.
12) We need a swing clear hinge for an ADA clearance problem. Is the 641 the right part?
No. The 641 is a standard full mortise continuous hinge and the door still swings on the frame line, so it does not recover the door thickness in the clear opening. For a swing clear condition, the ABH A210HD full surface swing clear continuous hinge is the type that pulls the door leaf out of the opening.
13) Does it matter that the BEST 641 is steel while most of the alternatives are aluminum?
It matters for how you finish and where you use it. The BEST 641 is a steel full mortise hinge with stainless steel bearings top and bottom, and is supplied in a 600 primed-for-painting finish that is meant to be field painted to match the door. The ABH A120HD, A135HD, A210HD and A460HD are aluminum continuous gear hinges, as is the Pemko FM-RG Series, and the NGP HD5400A is an aluminum alloy hinge. Aluminum geared hinges are typically supplied in an anodized finish rather than a paintable primer.
