Ultra Delay slip block
The Ultra Delay slip block guarantees optimum closure of all ALWECO screen installations, all year round, even in extreme cold or heat. The clever design of this slip block means that there is a balance between the block and the drive cable, so that tipping is no longer possible.
Assembly of the UV-stabilised and wear-resistant Ultra Delay slip blocks is very simple. No bolts or nuts are needed. The spring system provides a constant spring pressure, so that the slip block never blocks.
The Ultra Delay slip block can of course be used on all our own screen profiles, but also on almost all other common screen profiles and 19 mm tubes.
