FREQUENTLY ASKED QUESTIONS

Q: Does the location of the template angle tabs matter when riveting them to the cardboard template?

A: The pairs of template support tabs should be evenly spread along the outside cardboard template edge to make it easier to align on the trailer edge. Although the exact locations are not important, the template will lie better on the trailer door if you avoid placing the template tabs over the existing trailer door hinges.

Q: How do you know which holes to use on the template and drill through the trailer door?

A: While holding the template up to the door in the correct position, look along the outside trailer edge for any interference with existing trailer door hinges. These holes will NOT be used and do NOT require drilling. Find the four pairs of transfer marks for lateral hinges that will be used for the lateral panel—these will require drilling for elevator bolt placements. For custom TrailerTails®, drill all of the holes.

Q: How determine the vertical location of the template?

Generally, a good rule-of-thumb is to align the template just under the top trailer lights, ¼” to ½” clearance below the top lockrod’s claw.

Q: Does it matter which panel you start with?

A: No. It is possible to install a TrailerTail® in any order although following our recommended process will make installation easier and faster.

Q: Does it matter which direction the rod ends face?

A: Yes. The TrailerTail® will not fold correctly unless the threaded bolt of the rod end points towards the trailer door.

Q: There are two different lengths of 5/16” bolts—3.75” and 4”. How do you know which one to use?

A: There are 8 locations on the TrailerTail® that require the 3.75” bolts: where the top and bottom panel hinges attach to the trailer door. 4” bolts are used for both the lateral hinges and the metal origami hinges where the lateral panel connects to the top and bottom panels.

Q: How long does a TrailerTail® installation take?

The TrailerTail® for dry van trailers is designed for 2 people to install in 1 hour.  The current record installation time is 2 people in 28 minutes.  Refrigerated trailers require 2 people for 1.5 hours due to specialized attachment hardware.

Q: How do I purchase TrailerTail® technology for my fleet?

A: TrailerTail® is available direct from ATDynamics, from your local trailer dealership and OEM installed.  For more information
