Hey Derek, welcome back! To convert your wooden bunks to rollers, I recommend the 5' Long Tie Down Roller Bunks for Boat Trailers item # TD74FR. These come in a pair and are 5' long. Each roller bunk includes six sets of black rubber rollers. The bunks themselves are made of galvanized steel so you don't have to worry at all about rust or corrosion.

We also have the 4' Long Tie Down Roller Bunks for Boat Trailers item # TD64FR. These have 5 rollers each but are made of the same material. They're just a foot short and have one less set of rollers.

To attach the roller bunks to your trailer's frame, you'll need to use swivel bolster brackets. Which ones you need are going to be determined by how high you want the roller bunks to sit. You'll need two brackets for each roller bunk. I have listed our options below:

8" Long - Qty 1 item # TD54FR

10" Long - Qty 1 item # TD34FR

12" Long - Qty 1 item # TD94FR

How long are your wooden bunks and what kind of boat do you have?
