With locking slide units GN 147.7, recurring positions along a square construction tube can be moved to easily and quickly. The required holes for type R or countersinks for type D can be created by the user according to the design instructions or ordered as completely finished construction tubes with locking holes GN 990.1. 

They can be replaced by clamping kits  GN 911  (see dimensions table for order designation) for fast and tool-free slide unit clamping. Centering bushings in the pass-through holes eliminate the axial play between the top and bottom parts of the locking slide units.

Locking slide units GN 147.7 are delivered with unmounted locking bolts (type R) or spring-loaded spacers (type D). Type G with thread is universally suitable for specific applications.
