The SL57 full surface geared continuous hinge is a long-term, tamper-resistant solution for your high-traffic commercial entryways. Designed for retrofit or new construction applications, it will reduce maintenance costs while outperforming traditional butt and pivot hinges. Here’s why it is the best choice in schools, offices, airports, storefronts, hotels and public and industrial buildings :
- Lasts 60+ years in high-traffic entryways. A SELECT geared continuous hinge distributes stress the full length not just two to four points along the door so it performs problem-free for years. To prove its superior endurance we tested a SELECT hinge for 25,000,000 open/close cycles (equivalent to 60-years of high-traffic operation) and there was no measurable change to the hinge or door.
- Backed by our exclusive Continuous Warranty™ — that proven endurance deserves a warranty that never ends for a hinge that never quits.
- Reuse doors and frames. No need to start over when installing an SL57 geared full surface continuous hinge.
- SL57 hinges fit doors better and last longer because the matched leaves are manufactured, machined and anodized after machining — together.
- Consistent templating ensures hinge holes line up precisely which simplifies installation.
- Lifetime lubrication delivers quiet performance; eliminates periodic maintenance.
- Qualifies for LEED points. SL57 hinges are made from up to 100% recycled aluminum and their durability reduces environmental impact.
- Ships in 48 hours. 99% of all SELECT hinge orders are "Geared to ship in 48 hours." You will be able to start improving your building’s security and cost savings in days, not months!

Select Hinges SL57-95-CL-SD – Frequently Asked Questions
1) Can I install a Select Hinges SL57 continuous hinge on an existing door and frame, or do I have to replace them?
Existing openings are the point of the SL57. It's a full surface geared continuous hinge, so both leaves screw to the face of the door and the face of the frame rather than into a mortised pocket, and the door and frame stay in service. That makes it the type to reach for when butt hinge pockets in the hinge edge are torn out or elongated from years of traffic, since the new fastening picks up fresh metal on the faces instead of the chewed-up edge. Select templates the leaves consistently, so the hole pattern lines up the same way opening to opening across a building.
2) Is the Select Hinges SL57 continuous hinge fire rated?
The SL57 carries a fire rating and meets ANSI/BHMA A156.26-2006 Grade 1, the standard written specifically for continuous hinges. For a facility spec that calls out a Grade 1 continuous hinge on a labeled opening, that's the pair of lines the SL57 answers to. Confirm the length and thickness you order match the door on the label.
3) Should I use a continuous geared hinge or stay with butt hinges on a high traffic entry door?
Butt hinges carry the whole door weight at two, three or four points on the hinge edge, and on an entry that cycles all day those points are where the screws work loose and the door starts to sag and drag the frame. A geared continuous hinge like the SL57 spreads that load down the entire height of the leaf instead, which is why it's specified on school, office, airport, hotel and storefront entrances. Select ran one to 25,000,000 open and close cycles with no measurable change to the hinge or the door. If the door is already sagging on butts, the continuous hinge is the fix rather than another set of butts.
4) What screws and fasteners come with the Select Hinges SL57, and do I need to drill the frame first?
Fastening is 12-24 x 3/4 inch self drilling, thread forming 410 stainless Phillips undercut flathead screws, plus 1/4-20 through bolts and 1/4-20 shoulder screws. The self drilling screws cut their own hole in hollow metal, so there's no separate pilot drilling and tapping step on a standard frame. The through bolts are what you use through the door leaf on the heavier or higher abuse openings where you want the fastening pulled through rather than held in one skin.
5) Does a continuous hinge make an out-swinging exterior door harder to attack than butt hinges with pins?
Yes, and it's a common reason security integrators move an out-swinging exterior door to a hinge like the SL57. There's no pin to pull and no knuckle to cut, because the geared leaves interlock down the full height of the door instead of pivoting on removable pins at three points. Select lists the SL57 as a tamper-resistant solution for commercial entryways for that reason.
6) What finishes does the Select Hinges SL57 come in for matching the rest of the doors in a building?
Two finishes: clear Anodized Aluminum and Dark Bronze, both offered in all three lengths (83, 85 and 95 inches). Clear anodized is the usual match for aluminum storefront and mill finish frames, dark bronze for bronze anodized storefront and darker painted hollow metal. The leaves are anodized after machining as a matched pair, so the two halves come out the same shade rather than being finished separately and mismatching on the door.
7) Does the SL57 continuous hinge need to be oiled or serviced once it's on the door?
No scheduled service. The SL57 runs on thrust bearings and is lubricated for life at the factory, so there's no periodic greasing on the PM route and no squeak developing as the bearings dry out. That's the practical difference on a fleet of doors: a continuous hinge that stays off the maintenance list, where butt hinges keep coming back for tightening and lubrication.
8) Do continuous geared hinges help on a LEED project?
They can. SL57 hinges are made from up to 100 percent recycled aluminum, and Select states the hinge qualifies for LEED points on that recycled content and on the service life, since a hinge that doesn't get replaced is material that doesn't get consumed. If you're documenting recycled content for a submittal, it's the aluminum content line you'd cite.
