For industrial safety gate installation, mount the hinge as close as possible to the top of guardrail. Ideally, the top bolt hole should be located 1” down from the top rail, but this may need to be adjusted depending upon the guardrail members. Typical measurements are shown in drawing below.
Position two 9/16” holes on 6 1/4” centers for two 1/2” carriage bolts (4” top and 5” bottom). Holes should be positioned to allow clearance for tightening 1/2″ nuts.
SUPPORT BLOCK **INSTALLATION NON-OPTIONAL!**
Mount the block so that it is positioned at least 1” BELOW the closed bar. Allow clearance for tightening the 1/2” nut.
Position one 9/16” hole for mounting the block with the 1/2” x 4” carriage bolt.
Block should not interfere with the opening or closing of the industrial swing gate. It is intended to provide vertical support in an emergency. The block should be located at least 5″ below where the top of the hinge is positioned.
