4" x 12" Aluminum Bunk for Tritoon

4-inch by 12-inch bunks are used to convert your 5,000 - 9,000 lb or 10,000 - 13,000 lb 4-piling boat lift into a tritoon boat lift. The 4-inch aluminum bunks are made for a 6-inch or 8-inch I-beam. You will have no rust or wood rot worries with the vinyl pad.

These are the outer bunks from the tritoon kit. These bunks are sold individually or can be purchased as part of the tritoon bunk kit. 

Hardware to attach the bunk to the brackets is sold separately. You will need the Tide Tamer bunk board hardware package for 5K to 13k boat lifts or Bunk Board Hardware PKG for 16k to 24k lifts.
