QxV Sectional Door


High Performance

Durability and soaring energy costs continue to be a challenge in the loading dock industry. DL Manufacturing has come up with an affordable solution that eliminates air and light gaps in the QxV Flexible Sectional Dock Door. The key to our design is a rugged, flexible PVC panel with an R-value of R-22 which is why QxV surpasses the performance of other sectional dock doors.

This makes QxV an ideal solution for any overhead door or cold storage application.
