C.E. Smith 29553 Jon Block 3" x 3" Rubber Bow Stop

The C.E. Smith 29553 Jon Block is a marine-grade rubber bow stop designed specifically for jon boats and flat-bottom boat trailers. This durable black natural rubber block provides a flat contact surface that perfectly matches the bow profile of jon boats, ensuring even load distribution and secure positioning during transport and storage.

Key Features:

• Marine-grade black natural rubber construction for long-lasting durability in harsh conditions
• 3" x 3" flat contact surface ideal for flat bow jon boats
• 1/2" inner diameter shaft mounting for easy installation
• Acts as a cushioned bumper to prevent bow-to-winch contact during loading
• Replaces original equipment on most boat trailers
• Fits standard 3/4" shafts with proper brackets

This jon block serves as a critical trailer component, keeping your boat's bow securely in place while preventing damage from direct contact with the trailer winch. The flat design distributes stress across a wider contact area compared to rollers, minimizing hull stress and protecting your investment during trailering, launching, and loading operations.
