What are spacer blocks in window blinds?
window blind spacer block
Spacer blocks are designed to push the window blinds away from the wall or door in which they are mounted. Most outside mount blinds, those window blinds mounted outside the window frame, do not require spacer blocks. Occasionally objects such as trim or molding may interfere with the blinds. To provide proper clearance, a spacer block is inserted between the window blinds and the wall.

Spacer blocks can vary from one manufacturer and virtually anything could be used as a spacer block. If a spacer block is needed, the valance returns should be extended or made longer to cover the additional distance the blinds will be from the wall. Upon ordering, Blinds Chalet will custom make longer returns for this purpose if notified.
