Integra glide hooks for Monorail and Decorail, also used on the Aluglide and Decorail curtain rails.
Glide hooks allow for separate curtain headings, so that you can remove the curtains and have them cleaned and still have some privacy using the linings.
Integra Monorail and Decorail curtain tracks were cheaper plastic tracks which used these Integra glide hooks and the Aluglide was good quality steel track.
All of these Integra tracks used these Integra end stops.
