JFATXTT 4" Boat Trailer Bow-Stop Roller — 4" Diameter, 1/2" Steel Shaft, Non-Marking Rubber

A heavy-duty 4" rubber bow-stop roller with a 1/2" steel shaft that protects hulls and eases launching and retrieval on boat trailers.

The JFATXTT 4" Boat Trailer Roller Bow Stop with 1/2" Shaft is built to smooth the contact between your boat and trailer while resisting marks and abrasions. Made from quality non-marking rubber over a sturdy metal core, this roller is sized for a wide range of small to mid-size boats and fits common trailer mounts. It reduces friction and helps center the bow during loading, minimizing bumps and scratches that happen at launch ramps and storage drives.

How does this roller protect my boat during launching?

The rubber construction cushions impact and prevents metal-to-hull contact, so the boat rides up and down the trailer without scuffs. The roller’s shape distributes pressure evenly across the hull lip, reducing stress points that cause chips or paint damage.

• Non-marking rubber avoids scuffs on gelcoat and paint
• 4" diameter offers broad contact area for better load distribution
• 1/2" shaft gives secure fastening to standard trailer brackets
• Rounded profile guides the bow into center during retrieval

Will this fit my trailer and boat size?

This roller is sized to work with most small to medium trailers and boats, especially bow-stop and guide applications. The 1/2" shaft fits common mounting holes or brackets; measure your existing shaft hole and bracket clearance before purchasing for a perfect fit.

• 4" roller diameter suitable for dinghies to medium runabouts
• 1/2" shaft accommodates many trailer brackets and clamps
• Works as a bow stop or guiding roller depending on mount position
• Compact footprint for trailers with limited space at the bow

How durable and low-maintenance is the JFATXTT roller?

Constructed from long-lasting rubber bonded to a metal shaft, this roller resists cracking, flat-spotting and wear from repeated launches. Low maintenance means occasional rinse and inspection; replace if the rubber shows deep cuts or severe deformation after heavy use.

• Quality rubber resists abrasion and UV degradation with normal care
• Metal 1/2" shaft resists bending under typical loads
• Easy to install and remove for seasonal inspection or replacement
• Minimal upkeep—wash and inspect hardware periodically

How simple is installation and what hardware is needed?

Installation is straightforward on trailers that accept a 1/2" shaft roller: slide the shaft into your bracket, secure with a pin or fastener, and confirm the roller turns freely. If your trailer uses a different shaft diameter or bracket design, an adapter or new mounting hardware may be required.

• Slide-on installation for compatible 1/2" shaft brackets
• Secure with cotter pin, bolt, or retaining clip depending on trailer
• Check clearance so roller spins and centers the bow smoothly
• Adapters available if your trailer uses a different shaft size
