The Series 3000 may be an alternate selection when space limitations or other considerations preclude the use of a rigid dock shelter.

The shelter is normally in the extended position and uses spring tension to hold the curtains tight to the truck body upon vehicle entry.

A split head curtain further adds to this unit's versatility in servicing a wide range of vehicles. A combination of our superior performance materials guarantees this unit will withstand the most demanding requirements.

Series 3000 Alternate
Series 3500 - Similar to the 3000 but having tapered side curtains and bottom draft pads in lieu of 18" vertical foam blocks.

Suggested Specification:
Cover fabric to be Dynaflex, or other fabric as specified. Frame members, 2" x 6" raked header and 2" x 12" sides to be pressure treated wood, kiln dried before and after treating. (Steel frames are optional.) Unit to include upper and lower spring bias tension arms of 3/4" I.D. galvanized pipe which are designed to maintain the cover taut in the extended position. The tension arms and the top cross bar, upon entry of vehicle, shall have horizontal and vertical movement provided by the means of self-lubricating steel trolleys rolling in steel formed tracks.
