Tie Down Ladder Standoff Stabilizer for TranzPorter Hoist Track
The 48599 standoff stabilizer mounts near the top of the TranzPorter track and holds the rails off the gutter and fascia, so the hoist bears on the roof structure instead of crushing the gutter. It also widens the footprint at the top of the track for a steadier run.
It is built exclusively for the TP250 and TP400 and pin-locks directly to the hoist track in seconds. Keep it on the truck for every job with a gutter.
