Trailer Top Seals
Allmark Door Trailer Top Seals combine weight with gravity, and provide a constant seal across the top of the trailer, creating a dam which forces the water to run off the sides. The dam creates a barrier against wind, insects, dust and light. Trailer Top Seals can be installed on their own or retrofitted to existing units. Allmark Door offers a complete line of Trailer Top Sales with simple effective designs that do not require maintenance.
