Extreme Max Single-Post Horizontal Bunk Guide-Ons serve more than just helping you load your boat onto the trailer - they also address a multitude of loading issues. These guide-ons enable faster and safer loading, prevent you from loading too deeply, keep your trailer position accurate, and are particularly useful at night. They are designed to fit bunk or roller-style trailers up to 3" wide x 4.25" tall*.

The 18" carpet-padded horizontal bunks are positioned on 96° angled vertical arms, which can be adjusted horizontally up to 19" (for 3" trailer frames) or 21" (for 2" trailer frames). Vertically, the guide-ons are adjustable from 19" to 25" in height.

Extreme Max Guide-Ons are zinc-coated and intended for freshwater use only. Using them in saltwater or brackish water will damage the finish.

For taller trailer frames, there are two bolt kit options available: a 7" bolt kit for frames up to 5.25" tall (Extreme Max 3005.4050) and an 8" bolt kit for frames up to 6.25" tall (Extreme Max 3005.4053).

The product includes a pair of carpet-padded boat trailer guide-ons, which are perfectly suited for 14' to 16' boats. They can be used with both bunk and roller-style trailer frames up to 3" wide x 4.25" tall*.

The 18" carpet-padded bunks can be vertically adjusted from 19" to 25" and are mounted on 96° angled vertical arms. These arms provide up to 19" (for 3" trailer frames) or 21" (for 2" trailer frames) of total horizontal adjustment.

It's important to note that the size and shape of trailer frames can vary significantly, so it's recommended to measure your boat on the trailer before placing an order to ensure a proper fit.
