Available in a single pack (Part No. 21-001060) or a deluxe two-pack (Part. No. 21-001070), the Chock & Lock eliminates the front-to-back rocking motion in an RV by anchoring the opposing wheels of tandem axle trailers and fifth wheels, according to Ultra-Fab. When engaged, the trailer wheels actually work against each other to arrest any created motion regardless of ground surface or slope.

The Chock & Lock includes a tough, all-steel construction and corrosion-resistant zinc plating, according to Ultra-Fab. The Chock & Lock installs in seconds with an “easy-to-use” lever that expands the product to 5-inches and collapses it to 1.5-inches. 

Ultra-Fab recommends its Ultra Chock & Lock XL (Part No. 21-001080) for larger tire spacing. The XL model features all of the attributes of the deluxe model but it collapses to 4.25-inches and expands to 10-inches.

The Chock & Lock can be locked with a padlock for additional security, according to Ultra-Fab.

Ultra-Fab's Ultra Chock & Lock products are available through Arrow Distributing, NTP, Stag-Parkway, Bell and Northern Wholesale.
