Two Revolutionary Heavy Duty Hinges

HD300 AND HD600 HINGES SWING PRECISELY FOR DECADES

SELECT’s continuous hinges outlast any others on earth, but being the best isn’t good enough. Our innovators never stop finding ingenious ways to improve our hinges. SELECT’s newest heavy duty hinges — the HD300 and HD600 — are proof. These hinges’ strength and durability are exactly what you need at your entrances, so we discontinued our Standard Duty (SD) line.

Unmatched engineering delivers unsurpassed performance

• All SELECT geared continuous hinges (excluding SL38 & SL62) now conform to BHMA Standard ANSI/BHMA A156.26 Grade 1.
• Customizable to your door’s weight and frequency for seamless swinging precision.
• Superior solution for high-use or high-abuse light to mid-weight hollow metal and storefront doors. Once installed, you will not do one minute of maintenance or make any adjustments on these hinges for decades — and more likely, forever.
• In stock and ready to ship fast!

Load/Frequency Rating

SELECT Load/Frequency ratings are based on entrances with 1-3/4"44.45 mm doors (max. 48"1219 mm door width) in 16 gauge hollow metal (min.) or 1/8"3 mm aluminum (min.), except where noted.

• Low-frequency = 40x per day or less
• Medium-frequency = Up to 80x per day
• High-frequency = More than 80x per day and/or abused doors (ones that often get slammed against a stop, operate in a school, etc.)

Frequency of use and door weight determine the hinge duty needed.
