Telescoping doors

Telescopic automatic sliding door

ASSA ABLOY SL500 Telescopic - telescoping door for exceptional performance

Automatic telescopic doors offer a great benefit when space is limited. By incorporating an additional sliding door active leaf, a telescopic automatic sliding door allows you to gain additional clear door opening, particularly welcome in the tightest of spaces.


The ASSA ABLOY SL500 Telescopic is an automatic telescopic door that sets a new standard in telescopic performance by providing superior support and stability. By utilizing an exclusive “door on door” design, the ASSA ABLOY SL500 Telescopic automatic sliding door has an innovative design that improves upon inferior suspended track systems. It places the door weight on the structural portion of the automatic door header via two structural boxes with integrated replaceable aluminum tracks.

ASSA ABLOY SL500 T67 telescoping door - engineered to fit the smallest space

Until now, the average pair of 3’0” x 7’0” manual swing doors could be challenging to navigate due to the limited 32” (813mm) clear door opening, small footprint and cross-traffic concerns. Enter the revolutionary ASSA ABLOY SL500 T67 telescopic automatic sliding door. Specifically designed to fit the same door opening provided by a pair of 3’0” x 7’0” manual swing doors, only a minimum of 72” (1829mm) of overall frame width* is required to transform your entryway with no less than 46” of the usable door opening. Whether it be new construction or retrofit applications, look to ASSA ABLOY SL500 T67 telescopic doors to automate virtually any small entryway.
