Core Trax 1000 tie-down tracks are made from 6061-T6 aluminum alloy and powder coated silver. They are custom manufactured to align with the steel tubes in your DECKED deck's subframe, allowing you to mount extra hold points on top. The track can be oriented towards the cabside or tailgate side of your truck bed. The 4 attachment loops can be placed at 1" increments along the trax. These DECKED custom Core Trax 1000 are beveled 45 degrees at both ends to avoid snagging your stuff.
