Tie Boss 3/8" Heavy-Duty Self-Locking Tie Down System — 15 ft Orange Rope, 300 lb Jam Cleat

The Tie Boss 3/8" heavy-duty self-locking tie down system is a durable, American-made jam cleat rig that secures up to 300 pounds with a 15 ft polypropylene rope and included hooks.

Designed for hauling, hoisting, and securing gear without knots or unreliable elastic cords, this Tie Boss kit replaces fiddly fasteners with a simple pull-and-lock jam cleat. Built from weather-resistant nylon with no moving metal parts, the orange 3/8" rope assembly is compact, easy to install, and intended for indoor and outdoor use where predictable tension and quick release matter.

How does the Tie Boss lock and release loads safely?

The jam cleat captures and holds the rope under tension so the line won't slip while carrying or suspended. To secure a load you simply pull the rope through the cleat until tight; the line seats under pressure and remains locked. To lower or loosen, lift the rope slightly and pull it free—no knots, buttons, or complex steps required.

• Patented jam cleat design holds constant tension without tie-offs
• Releases by lifting rope to a small angle for smooth lowering
• No spring-loaded parts to corrode or freeze

What load size and rope specs should I expect from this system?

This Tie Boss kit uses a 3/8" solid-braid polypropylene rope and is rated with a 300 lb working load limit suitable for many light- to medium-duty tasks. The kit includes 15 feet of rope—enough for hoisting bicycles, kayaks, cargo netting, or garage-stored items. For heavier industrial use, choose a system rated for higher capacities.

• 3/8" diameter solid-braid polypropylene rope, 15 ft included
• 300 lb working load limit for typical residential and recreational uses
• Comes with one G-hook and one S-hook for versatile anchor points

Can I use Tie Boss outdoors and will it last in weather?

Yes—the cleat and components are made from heavy-duty nylon and polypropylene that resist rust, freezing, and common outdoor wear. Because there are effectively no metal moving parts on the cleat itself, the risk of seizure from corrosion is minimized. Regular inspection of the rope is recommended since the rope is the only part excluded from the lifetime warranty.

• Weather-resistant nylon jam cleat resists rust and freezing
• Polypropylene rope designed to withstand moisture and routine outdoor exposure
• Manufactured in the USA at a Piqua, Ohio facility with quality control

What comes in the box and what warranty coverage applies?

The kit ships with a Tie Boss jam cleat, 15 ft of solid-braid rope, one G-hook, and one S-hook—ready for mounting and use. Tie Boss offers a limited lifetime warranty on all parts except the rope, which is considered a wear item. Installation hardware and anchor methods will vary by mounting surface, so plan fasteners appropriate to wood, metal, or masonry.

• Included: jam cleat, 15 ft rope, G-hook, S-hook
• Limited lifetime warranty on parts (rope excluded)
• Made in the USA with manufacturer support available
