Product Overview Extension cord for Autoslide automatic sliding door opener, available in white or black. Reviews (1 review) Write a Review 1 Review Hide Reviews Show Reviews 5 Works great!. Posted by Christine Stephenosn on Jan 23rd 2019 Cord from autoslide did not quite make it to outlet, so instead of having an extension that did not look so great we ordered this cord. Fits great, not as bulky as a regular extension cord. Easier to conceal.
