T-Rail Guide: Standard vs Vertical

Fitment help

Our rail-mount products come in two versions because boat builders put the T-slot track on two different faces. Look at the face your track sits on. That face tells you which option to pick.

Cross section of a standard angle T-rail: the T-slot face leans in toward the deck at about 45 degrees, with a bracket sitting flat on it. CROSS SECTION 45° FACE < INSIDE OF BOAT OUTSIDE > leans in about 45°

Standard Angle T-Rail

The track face leans in toward the deck at roughly 45 degrees.

Most T-rail boats. Standard brackets are bent to sit flat on that slope.

Cross section of a vertical T-rail: the T-slot face is straight up and down on the inside wall of the gunnel, with a square-bent bracket sitting flat on it. CROSS SECTION VERTICAL 90° FACE < INSIDE OF BOAT OUTSIDE > straight up 90°

Vertical T-Rail

The track face is straight up and down, usually on the inside wall of the gunnel.

Some brands and models. Vertical brackets are bent square to sit flat on that wall.

How to check in 30 seconds

  1. Stand at the side of the boat and look down the rail from one end so you can see its shape.
  2. Find the T-slot, the narrow groove the mounting bolts slide into.
  3. Look at the face that groove is cut into. Leaning in toward the deck means Standard Angle T-Rail. Straight up and down means Vertical T-Rail.

Why it matters

Each bracket is bent to match its face. The right one sits flat with no gap. The wrong one sits tilted and will not pull down tight.
