Select Hinges SL84 Concealed Geared Continuous Hinge

Specifications and Installation Instructions

Product Overview

The Select Hinges SL84 Concealed Geared Continuous Hinge is designed for high-traffic applications, offering durability, security, and a clean aesthetic. It eliminates visible screws and provides a weatherproof, tamper-proof barrier when the door is closed.

Specifications

Materials

Extruded 6063 T6 aluminum alloy with self-lubricating polyester thrust bearings.

Lengths

Standard lengths: 83" and 95" for nominal door heights. Custom lengths are available.

Load/Frequency Ratings

Standard Duty: For 1-3/4" doors, up to 48" max. door width in 16 gauge hollow metal (min.) or 1/8" aluminum (min.).

Heavy Duty (HD): Tested per BHMA standards. Up to 200 lb. doors (high-frequency) and up to 400 lb. doors (medium-frequency) without frame or door reinforcement. Up to 600 lb. doors (low-frequency) with the use of Rivnuts in the frame and door.

Heavy Duty (LL): For low-frequency doors up to 1,000 lb., including most lead-lined doors. Rivnuts are recommended for extremely tall, heavy, or wide doors.

Finishes

Standard finishes: Clear and Dark Bronze anodized aluminum. Custom anodized or painted finishes are available. Field painting or anodizing voids the Select hinge warranty.

Closers

Compatible with conventional overhead surface, concealed sliding arm overhead, or floor closers. Pivot-type floor closers with a fixed center pivot must be replaced.

Select Hinge Performance

The SL84 geared continuous hinge has been tested to exceed 25,000,000 cycles, providing over 62 years of performance at 400,000 cycles per year. It is designed to handle abuse from high-traffic applications and integrates the door and frame into a single unit, dissipating stress along the entire length.

The hinge eliminates the gap between the door and frame, creating a weatherproof, rust-proof, and tamper-proof barrier. There are no accessible screws, bolts, or pins when the door is closed.

The SL84 hinges are listed and tested by Underwriters Laboratories for positive and negative pressure requirements (UL10B and UL10C) and meet UBC 7.2 (1997). They are suitable for swinging single fire doors up to 4'x10' or pairs of fire doors up to 8'x10' in masonry or drywall. They are rated for up to 1-1/2 hours for wood core fire doors, with an optional 3-hour rating for hollow metal or steel-covered composite doors.

Installation Instructions

Tools Needed

Metal-cutting saw
Tape measure
#13 or 3/16" drill bit
5/32" drill bit (for wood frames/doors)
#3 Phillips drive
Shims

Parts Supplied

#12-24 self-drilling, thread-forming (SDTF) 410 SS Phillips undercut flathead screws

Optional Parts

#12 410 SS Phillips undercut flathead wood screws
#12-24 thread-forming (TF) 410 SS Phillips undercut flathead screws
Protective gloves (recommended)

How to Cut the Hinge to Fit

Keep the hinge in the "door closed" position (Fig. 1).
Determine if the installation is right-hand or left-hand.
Important: Cut only one end of the hinge. The cut end will be installed at the bottom. Keep the original templated six-hole pattern at the top end. (Note: SL11, SL27, and SL38 are non-handed and remain so after cutting).
Using a metal-cutting saw, cut through the gear cap first. Do not cut through a set screw bearing.
Reinstall any set screw bearing that may have been cut off.

Preparing the Frame

Shim the hinge 1/8" below the header to allow for door clearance.
Hold the hinge in the "door open" position (Fig. 2), ensuring the frame leaf alignment flange is tight against the frame face.
Mark or centerpunch hole locations. Note: TF and wood screws require pilot holes at marked locations. SDTF screws do not require pilot holes.
If using SDTF screws, proceed to step 5. If using TF or wood screws, drill pilot holes at marked locations. Do not attach the hinge to the frame at this time.
- Metal frame: Use #13 (.185") bit or 3/16" (.188") bit.
- Wood frame: Use 5/32" (.156") bit.

Attaching the Door to the Hinge

Align the door leaf alignment flange or the door leaf lip along the full length of the door edge, even if the door is slightly warped.
Mark or centerpunch holes. If using SDTF screws, proceed to step 7. If using TF or wood screws, drill holes at marked locations.
- Metal door: Use #13 (.185") bit or 3/16" (.188") bit.
- Wood door: Use 5/32" (.156") bit.
Fasten the door leaf to the door using #3 Phillips drive and provided fasteners.

Attaching the Door to the Frame

Position the door at 90 degrees to the frame. Shim the door to the proper height so it aligns with the top screw holes.
Install two screws at the top of the hinge. Remove the shim and align the remaining holes. Install screws in the middle and bottom two holes.
Check the door for proper swing and clearance before installing the remaining screws.

Reinforcing & Rivnuts®

No hinge reinforcement is typically necessary, except for extremely high-frequency, heavy, or extra-wide doors. Rivnuts are recommended for the frame when the door exceeds 450 lb. (max. 600 lb.). Only Select steel Rivnuts should be used with fire-rated Select hinges.

Grouted/Slushed-in Frames

For ease of installation, it is recommended to install a mudguard behind the frame. Do not use self-drilling, thread-forming (SDTF) screws to drill into grouted frames. If mudguards have not been used, carefully drill pilot holes through the frame and remove grout for screw clearance. Do not oversize holes in the frame.

Fire-Rated Hinges

All stock Select hinges are 90-minute UL-rated without pins. Contact Select for complete information about its fire-rated hinges.

Calculating Required Door Clearances

For Square and Beveled-Edge Doors

Important: Standard length Select hinges are supplied slightly shorter than nominal door height to avoid threshold or flooring clearance issues. All uncut concealed hinges are non-handed and templated. Models SL11, SL27, and SL38 remain non-handed after cutting. All other concealed hinges become handed after cutting. Refer to NFPA 80 for clearance requirements on fire-rated entrances.

Single Door: Square Edge

Hinge side clearance: 5/16"
Latch side clearance: 1/8"
Frame variance clearance: 1/32"
Total Width Clearance: 15/32"

To determine door width: Subtract the Total Width Clearance from the width of the frame opening.

Single Door: Beveled Edge

Hinge side clearance: 5/16"
Latch side clearance: 1/8"
Frame variance clearance: 1/32"
Beveled edge clearance: 1/32"
Total Width Clearance: 1/2"
