Selective Systems installs TOSTEM's corner slider door for openings that want to erase the corner frame entirely. Fixed and sliding sashes meet edge to edge, running on a sloped drainage track with a low threshold — built for high-rise living, courtyards, and any space that wants a wraparound view.

Learn MoreCommon questions, answered.
What spaces suit a corner slider door best?
Bathrooms, balconies, kitchens, bedrooms, and commercial spaces that want a space-saving corner opening with large, uninterrupted glass panels.
How does the low threshold work?
A sloped bottom track channels water away from the opening while keeping the threshold low enough for easy access, including for children and wheelchair users.
Is a corner slider door as weathertight as a standard sliding door?
Yes — rubber gaskets and a sloped drainage track are engineered specifically for the corner condition, so sealing performance matches our standard sliding door range.
