Self Centering Boat Trailer Roller Kit | 2x2 Tube Sliders

A self centering boat trailer roller kit for 2 x 2 inch box trailers. Wind or tide walks a tinnie off the centre rollers. This Load Ya Boat wing catches the hull and guides the keel back onto the centre roller while you winch, and the tube sliders clamp the wing to 50 x 50 mm cross tubes.

It is the Wind Ya Boat setup: one galvanised winged bracket with stainless rivets, a 700 mm arm and a 6 inch roller, plus two adjustable tube sliders for 2 x 2 inch (50 x 50 mm) box steel. Leg height and angle set the wing just under the hull. Stated fit is aluminium boats to 5 m (16.5 ft).

In the box

• 1 x Load Ya Boat adjustable kit, 700 mm arm span, 6 inch roller
• Galvanised winged bracket with stainless rivets
• 2 x adjustable tube sliders for 2 x 2 inch box steel
• 2 x adjustable legs, bolts and lock nuts
• Guide skids for the wing

Not in this kit: a second wing, a clamp-on adjuster for round tube, or the maker’s Teflon-lined aluminium skids. Those aluminium skids are a separate part. If the trailer already has 19 mm double-stem brackets and no 50 x 50 mm box, use the self centering boat trailer roller kit without sliders ($230).

Which kit

• This page: winch-on, one wing, trailer cross tubes are 2 x 2 inch box.
• 19 mm double stems and no box tube: buy the $230 kit, not this one.
• Single-stem or round tube: add a clamp-on adjuster. These sliders are for square 50 x 50 mm only.
• Drive-on: fit a second wing on the next cross member. One wing is the winch kit.
• Telwater frames are often 75 x 75 mm. These sliders will not fit that tube. Measure before you order.

Install

Boat off the trailer. Tyres in the driveway, or the ramp car park if you can get it back on. Clamp the two tube sliders to the 50 x 50 mm cross tube and sit the wing on the adjustable legs. Boat back on. Set the height to the existing rollers, grease the threads, then lock the nuts. Let the skids stick out past the rear of the trailer so they catch a boat that comes in offline. About an hour with a shifter and a socket set.

A self centering keel roller is one grooved wheel. It helps after the keel has already found it. This kit is the guide in front of that roller. Use both if the centre roller is flat-spotted. The 8 inch red self centering roller is listed separately.

Maker fit note: adjustable legs cover most Australian tinnie trailers, alloy hulls to 5 m. Not the kit for a large glass boat.
