Installation of Caps

The successful use of a containment cap is as good as it’s fit with the spigot it mates to. If the hole cut in the cap is not perfectly round and it’s edges smooth it will not seal well. If the hole is oversized it will not seal well. If it is undersized it may wear prematurely. To optimize performance the hole must be cut properly.

To this end we have available an adjustable beam compass with several surgically sharp blades and compass point-centering guard. Use this kit to cut the holes in the containment caps to the diameter shown in the adjacent chart. The spigot/hole sizes shown will provide an optimum fit, providing you with optimum dust containment.

This compass kit can be purchased separately for $75.00 or is provided free of charge, with your first order of $600.00 or more.
