Using Magnapull<br />
A quick and easy way to protect overhead doors is to use the versatile<br />
Magnapull. There are no brackets to adapt and no drilling through thick steel<br />
tracks or channels. Magnapull is also ideal for overhead door applications where<br />
there is a lot of play in the door.<br />
Fasten cable using 1931 wire clamp so that if the switch is dropped it will not hit<br />
the floor.<br />
Mount the magnet housing at approximately a 20˚ angle from vertical to prevent<br />
switch damage if door is opened before switch is removed. The end user should be<br />
instructed to release the Magnapull switch before the door is opened to prevent<br />
damage to the switch.<br />
Position cable so there is slack between magnet housing and wire clamp.<br />
Test proper operation of switch by opening door.<br />
