Assa 82, 62, 34 manual Collapsing the Blind Nuts

Rev. A.3, 5/00 Page- 4

In step two, holes must be drilled for the mounting screws, and a 1/2" (12.7mm) diameter wire- way hole should be drilled. Step three is to install the blind finishing nuts. For proper strength, the 1/4-20 (or 6mm) mounting machine screws must be secured by these nuts. They will work on any thickness metal header and are used as follows: A 3/8" (9.5 mm) hole is drilled following the template for each nut. The nut is then pressed up into the hole and lightly seated with a hammer tap. The nut is then collapsed inside the header. If you have Securitron's IK installation kit, the nuts may be collapsed by the use of the blind nut placement tool. A special collapsing tool is also included with each Magnalock. It is somewhat slower to use than the more elaborate tool found in the installation kit. For its use, see Figure 3.

Step four is to make the necessary wire connections. Step five is to mount the magnet via the supplied machine screws (see Figure 1). Don't forget to use the gold flat washers. They prevent the narrow screw heads from digging into the resin which could cause damage. Tighten the screws to a snug fit only. Use the supplied thread-lockon the screw threads to avoid the possibility of the screws loosening over time. Do not drill out the mounting holes to make for an easier fit. You may cut an internal wire and void the warranty.
