LDC D500 loading dock retractable truck shelter

10’0” w x 10’0” h openings

Generally designed to suit 10’ wide x 10’ high openings. The series D500 provides full access to the rear of the trailer while creating a tight seal against the top and rear of the trailer. The collapsible frame is designed to retract upon impact from the trailer thus reducing pressure against the curtains and extending the life of the unit.
