I am renovating a "contemporary" style 1970s home. It has a lot of open space but can create private spaces thru the use of these Spacesaver wooden accordion folding wooden doors. Slats of wood are held together by rubber strips. One of the doors is in need of repair. The grooves that hold the rubber are splintered in some places so that the rubber strips will not stay in place and this of course creates gaps in the door when closed. Anybody know anything about repairing these doors or if this product is still manufactured? I have not been able to find anything on the web. Thanks!
