The Prop-N-Lock is made from 1″ thick aircraft quality aluminum, anodized for long-life and durability. It is manufactured by American craftsmen and assembled with high quality hardware.
The Prop-N-Lock has 1/8″ thick neoprene rubber cushions so that metal never touches any area of the door or doorframe.
Place the door frame clamp on the door frame. Try to use a door frame that allows you to completely bottom out the clamp to the door frame. This will create the ideal setup for the Prop-N-Lock to work best. Once the door frame clamp is in place, tighten by turning the black knob clockwise until the clamp is good and snug. Caution Hand tighten only. The use of pliers or wrenches will void the warranty.
Ensure that the nylon tip of the setscrew is flush with the inside of the door claw, then place it on the door, bottoming it out. Do not tighten yet. Holding the door claw in place, allow the door to close and line it up to the door frame clamp horizontally.
When the door claw is lined up, open the door using the supplied T-handle allen wrench, turn the setscrew to where it just contacts the door. Then tighten one-half turn maximum. Caution: Do not over tighten, damage to the door could result.
Make sure the compression knob is unthreaded far enough to allow the threaded pivot rod to slide into the door frame locking notch. Once the pivot rod is in place, tighten the compression knob ONLY far enough to make the door “rigid”. It is not necessary nor desirable to over tighten! Caution: Hand tighten only. The use of pliers or wrenches will void the warranty and possible damage the door or door frame.
Next, finger-tighten the lock nut snugly agains the knob. This will “lock” the compression knob, not allowing it to be easily loosened. This is an additional safety feature that would make it difficult for an outside individual to reach in and unscrew the compression knob. Should you wish to tighten a bit more than finger-tight, use the supplied T-Handle Allen wrench as a “spanner” wrench. Tighten an additional 1/4 turn AT THE MAXIMUM.
Use the T-handle to keep the compression locknut from turning, then turn the compression knob one-half a turn tighter maximum. Next, unscrew the compression knob lock nut, then unscrew the compression knob enough to swing out the pivot rod.
Viola! All the steps above will take well under a minute, normally about 40-45 seconds with very little practice.
Now you are all set to work in complete safety and security.
