Gardinia 14mm Run Up Block Upvc Riser White

This is a upvc runner lift up wedge type block that causes the opening sash to be lifted up into place as it close into the outer frame in cases where the opener has or is starting to drop or move downwards. The idea is that as the sash is forced onto this block the tapered wedge shape of it make it lift up into place so enabling the lock points to be forced into the correct position then enabling them to be able to operate and lock without causing un-due stress to the locking parts and hardware.

Tip: The upvc block has a universal shape to it however the outer frame it is been fitted to may require shaping to allow the block to sit firmly and flat on the upvc frame and then be fastened via the screw port hole. The block can also be shaped if necessary by use of a craft knife or sharp wood chisel.   Sold as a single item part as shown. Screws not supplied
