BEST BEST-651-UL-HT-630-6.8 – Frequently Asked Questions

1) Will the BEST 651 continuous hinge hold a heavy 600 lb commercial door?
Yes. The BEST 651 full mortise continuous hinge is rated to carry doors up to 600 lbs., and because the hinge runs the full height of the opening it spreads that load along the whole door and frame edge instead of concentrating it at three or five butt locations. The pin is 1/4 inch diameter, teflon coated, with two stainless steel bearings top and bottom to keep the door from sagging over time. That is the reason continuous hinges get specified on heavy lead-lined, high-traffic, or oversized doors that chew through conventional butts.
2) Can a BEST 651 continuous hinge be used on a 3-hour fire rated door assembly?
The 651 is fire rated for up to and including 3 hours, so it can go on fire door assemblies up to that rating. It also carries BHMA Grade 1-300 certification to ANSI/BHMA A156.26-2006. For institutional and MRO buyers writing a hardware schedule, those are the two lines that usually have to be satisfied on a rated opening, and the 651 answers both.
3) Do I need to mortise the door and frame to install a BEST 651 hinge, or does it surface mount?
Full mortise, so both the door edge and the frame rabbet have to be prepped to take the leaves. The hinge sits inside that prep and only a slim bevel shows when the door is closed. If your existing frame is not mortised and you do not want to rout it, this is the wrong configuration and you want a surface mounted continuous hinge instead, such as the ABH A460HD half surface or the Design Hardware full surface heavy duty geared hinge. Deciding mortise versus surface is the first call to make, because it changes what has to happen to the frame.
4) What is the closest equivalent to the BEST 651 continuous hinge from another manufacturer?
The BEST 651 is a full mortise continuous hinge with stainless steel construction, BHMA Grade 1-300 certification, and hospital tips included. The closest peer by mounting type and grade is the Pemko FM-RG Series, a Grade 1 aluminum full mortise raised geared continuous hinge with 180-degree swing. Design Hardware's FMHD full mortise continuous geared hinge is a heavy duty option in the same full mortise mounting family, and the ABH A120HD is a heavy duty aluminum continuous gear hinge in full mortise with Easy Install Technology. The distinction to confirm before ordering: the 651 is stainless steel, while the Pemko FM-RG and ABH A120HD are aluminum geared hinges.
5) The door and frame cannot be mortised for a continuous hinge - what continuous hinge should be used instead of the BEST 651?
The BEST 651 is a full mortise hinge, so it installs within routed pockets in both the door and the frame. When the opening cannot be mortised, a surface-applied continuous hinge is the substitute. Design Hardware's FSHD is a full surface heavy duty continuous geared hinge and the FSOHD is the full surface offset version. The NGP HD5700 is a full surface continuous geared hinge with 1/16-inch door inset for 1-3/4 inch to 2-1/4 inch doors. On the half surface side, the ABH A460HD is a half surface aluminum continuous gear hinge rated to 450 lbs, and the NGP HD5400A is an 83-inch half surface continuous geared hinge in aluminum alloy.
6) Which continuous hinge meets a Grade 1 spec on the drawing if the BEST 651 is not available in the length needed?
The BEST 651 carries BHMA Grade 1-300 certification to ANSI/BHMA A156.26-2006. Peers stated at Grade 1 include the Pemko FM-RG Series aluminum full mortise raised geared hinge, the Pemko CFM84SLF-HD1 84-inch full mortise short leaf flush heavy duty hinge, the Pemko FM-SLF short leaf flush geared hinge for 1-3/8 inch doors, and the Pemko DSH1000 anti-barricade hinge. The NGP HD1100A concealed continuous geared hinge is Grade 3, so it does not satisfy a Grade 1 line item even though its name reads heavy-duty.
7) The opening needs a fire-rated continuous hinge on hollow metal - how does the BEST 651 compare to the NGP hinges?
The BEST 651 is fire rated for up to and including 3 hours. The NGP continuous geared hinges are stated at a different rating: the HD1100A concealed hinge, the HD5400A half surface hinge, and the HD5700 full surface hinge are each 10C fire rated for 90 minutes on hollow metal. For a fire-rated assembly, match the hinge rating to the door label before ordering.
8) The BEST 651 has hospital tips - does that make it a safety hinge for a behavioral health or detention opening?
No. The BEST 651 ships with hospital tips, which close off the hinge ends for a clean, snag-free appearance in healthcare corridors. That is an end-cap detail, not an anti-ligature or anti-barricade function. For openings where a door must be opened against an obstruction, the Pemko DSH1000 is an anti-barricade Grade 1 continuous hinge with 100-degree bidirectional operation. The ABH A135HD is a heavy duty aluminum continuous gear hinge with safety design. These solve a different problem than hospital tips do.
9) Which continuous hinges come in a 96-inch or 120-inch length like the BEST 651?
The BEST 651 is offered in 80-inch, 84-inch, 86-inch, 96-inch and 120-inch lengths in 630 satin stainless steel. Among the geared peers, the fixed-length options run shorter: the NGP HD1100A, NGP HD5400A and NGP HD5700 are each 83 inches, and the Pemko CFM84SLF-HD1 is 84 inches. For a tall opening above standard door height, the 651 covers the length in a single hinge.
10) Are hospital tips included with the BEST 651, or do I have to order them separately?
Hospital tips ship with the hinge. Nothing extra to specify. Hospital tips are the angled end caps that eliminate the flat ledge at the top and bottom of the hinge, so clothing, IV lines, and cords cannot catch or be hung on it. That is why they get written into healthcare, behavioral health, and correctional specs, and it is worth knowing they are standard here rather than an upcharge line.
11) Will a stainless steel continuous hinge hold up in a wet or corrosive area like a kitchen, pool room, or exterior door?
Stainless steel construction with a 630 satin stainless finish is what makes the 651 a candidate for damp and washdown areas, natatoriums, commissary kitchens, and exterior openings where an aluminum geared hinge or a plated steel butt would eventually show it. Most of the continuous hinges on the market, including the ABH A120HD and A135HD, are aluminum gear hinges; if corrosion is the driver on your opening, stainless is the material distinction to hold out for.
12) What is the difference between the BEST 651 pin and barrel continuous hinge and a geared continuous hinge?
The 651 runs on 1/4 inch teflon coated pins with stainless bearings at top and bottom, a knuckle and pin design in stainless steel. Most competing continuous hinges are geared aluminum, where two leaves mesh through a gear channel with a cap over it, like the Pemko FM-RG raised geared full mortise or the ABH A120HD. Practical difference for a spec writer: the 651 gives you a stainless material and a 600 lb load rating with a 3 hour fire rating, while geared aluminum hinges are the usual pick where you want a lighter leaf and an aluminum frame match. Both are continuous, both distribute load full height.
13) I need Grade 1 continuous hinges to standardize across a facility. What else does ZenSupply carry besides the BEST 651?
The 651 is BHMA Grade 1-300 to A156.26-2006 in stainless. If you need Grade 1 in other mounting configurations to cover a whole building, the Pemko CFM84SLF-HD1 is a Grade 1 full mortise short leaf flush hinge in 84 inch, the Pemko FM-RG Series is a Grade 1 aluminum full mortise raised geared hinge with 180 degree swing, and the Pemko FM-SLF short leaf flush is Grade 1 for 1-3/8 inch doors, which is the one to reach for on older interior openings that are not 1-3/4. For a security or behavioral health application, the Pemko DSH1000 is a Grade 1 anti-barricade hinge with 100 degree bidirectional operation.
14) Which continuous hinge stays hidden when the door is closed - the BEST 651 or a concealed hinge?
The BEST 651 is a full mortise hinge installed within the door and frame, leaving only a slim hinge bevel visible when the door is closed. The NGP HD1100A is a concealed continuous geared hinge, 83 inches, Grade 3. If the appearance requirement is that nothing shows at the hinge edge, the concealed style addresses it; if the requirement is a Grade 1 hinge with a minimal exposed bevel, the 651 is the full mortise answer.
15) Is stainless steel or aluminum the right continuous hinge material for a wet or corrosive opening?
The BEST 651 is stainless steel with a 630 satin finish, selected for corrosion resistance in demanding environments. The geared peers in the same mounting classes are aluminum: the ABH A120HD full mortise, ABH A135HD, ABH A210HD and ABH A460HD are aluminum continuous gear hinges, the Pemko FM-RG Series is aluminum full mortise raised geared, and the NGP HD5400A is aluminum alloy construction. Material is the deciding difference on exterior, pool, kitchen and wash-down openings.
16) Which continuous hinge is easiest to install when retrofitting existing doors instead of the BEST 651?
The BEST 651 requires routing mortise pockets in both the door and frame to accept the full hinge leaves. On a retrofit where that prep is not already there, the surface-applied peers avoid the routing entirely - Design Hardware FSHD full surface, FSOHD full surface offset, and the NGP HD5400A half surface. If the opening is already mortised, the ABH A120HD is a full mortise aluminum gear hinge offered with Easy Install Technology.
17) Does the BEST 651 continuous hinge come in any finish other than satin stainless?
630 satin stainless steel is the only finish on the 651, across all five lengths. 630 is the standard commercial stainless finish and is what most schools, hospitals, and office buildings already run on their lever trim and push plates, so it usually matches an existing fleet without a second thought. If a facility is standardized on a bronze or dark finish, this hinge will not blend, and the visible bevel of a full mortise hinge is slim but not invisible.
