Specifications

Compatibility & Use

These Polyplastic Polyfix 300 mm auto stays are designed for Polyplastic opening windows found on many caravans, motorhomes and campervans. They work naturally with Polyfix slide-on brackets that clip into your existing window frame fittings to give a secure mount and smooth operation.

Before purchasing, check that your caravan/motorhome window uses the Polyfix clip-on system (deep groove on the back of the stay) rather than screw-on brackets to ensure correct fitment.
