A Widney slider is the only slider that is approved by Original Equipment Manufacturers. You are therefore assured of quality, functionality and reliability.
How do I tell a Widney slider from other, non OE sliders?
All Widney sliders have the word "Widney" screen-printed on them. If it does not say “Widney”, it is not an OE approved slider.
How is the slider mounted to the aperture?
A slider can be fitted using a glazing rubber, or it can be clamped on. Alternatively, the slider can be bonded to the aperture using a sealant. The most frequently used method is the glazing rubber.
