SELECT Hinge Performance
SELECT SL18 geared continuous hinges are listed and tested by Underwriters Laboratories to meet the Positive and Negative pressure requirements of UL10B and UL10C, and are in accordance with UBC 7.2 (1997). SELECT SL18 geared continuous hinges are for use on swinging single fire doors (max. door opening of 4'x10') or pairs of fire doors (max. door opening of 8'x10'), incuding double egress, installed in masonry or drywall. SELECT SL18 geared continuous hinges are rated for up to 1-1/2 hours for wood composite and wood core type fire doors. A special patented process can be added to increase the fire rating to 3 hours (NO FIRE PINS OR STUDS REQUIRED) for hollow metal or steel covered composite types doors.
A SELECT geared continuous hinge has been tested in accordance with ANSI 250.4-1994 test procedure and acceptance criteria for phyiscal endurance for steel doors and hardware and has surpassed 25,000,000 cycles during testing by an independent laboratory. On a door cycling 400,000 times per year, a SELECT hinge will be performing for over 62 years.
SELECT geared continuous hinges are built to handle abuse from high-traffic applications. They are applied to the surface on the edge of the frame and door. No machining or reinforcement is required.
The revolutionary SELECT geared continuous hinge puts an end to costly and irritating hinge failure problems, the most common cause of entrance failure.
On conventional hinges, opening and "kick-back" energy concentrate on a few inches of fastened reinforcing plate - with the top hinge handling 100% of the force. Pinless SELECT hinges bond the door and frame into an integrated, sag-free unit. "Kick-back" energy dissipates along the entire length of the door and frame. (Compare this to a conventional hinge's 4-1/2" to 5" at the top of the door and frame).
SELECT geared continuous hinges eliminate the gap between the door and frame providing a weatherproof, rust-proof, tamper-proof barrier. When the door is closed, there are no accessible screws, bolt or pins.
Material: Extruded 6063 T6 aluminum alloy with self-lubricating polyester thrust bearings.
Lengths: 83", 85", 95", and 120" lengths standard for nominal door heights.
Finish: All SL24 hinges are stocked clear and Dark Bronze anodized aluminum.
Load Frequency Ratings: For 1-3/4" doors. 48" max. door width in 16 gauge hollow metal (min.) or 1/8" aluminum (min.).
Standard Duty (SD) - Tested per BHMA standards for medium-frequency doors up to 200 lb. without frame or door reinforcement.
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 inforcement; up to 600 lb. doors (low-frequency) with the use of Rivnuts in the frame.
