Alweco

Ultra Delay slip block

Gaps are now a thing of the past.

Our Ultra Delay slip blocks guarantee that all ALWECO’s screen systems close fully all year round, in hot or cold conditions. Their ingenious design achieves a balance between the block and the drive cable such that skewing is eliminated. This exerts reduced loads on pull wires when opening and closing screens. Special-purpose springs allow the system to be adjusted for every conceivable situation.

Ultra Delay slip blocks are extremely easy to install. No nuts or bolts needed. The system requires no subsequent adjustment and springs provide constant tensioning that ensures that slip blocks never jam. The Ultra Delay slip block can be used on virtually all commonly available section and 19 mm tubing systems.
