Keep your slide-out secure and properly supported while driving. The Lippert 146364 raised travel block mounts under the RV floor to hold the slide-out in its retracted position during travel, preventing rattling, sagging, and wear on your slide mechanism over the road.
Slide-outs generate real stress on their mounting hardware when the rig is moving. A properly installed travel block acts as a brace point under the slide floor, distributing load and reducing the side-to-side movement that can accelerate wear on rollers, seals, and the slide room frame itself.
The Lippert 146364 is a raised-profile block designed specifically for slide-out systems where the block must clear the floor structure and contact the slide room from a higher mounting plane. The three evenly spaced mounting holes make for a straightforward installation with common hardware.
Elevated contact surface accommodates floor clearance requirements so the block properly contacts and supports the slide room when retracted.
Three evenly spaced 1/8 inch diameter holes for secure fastening to the undercarriage or floor framing with standard hardware.
Wide footprint spreads load across the slide room bottom, reducing point pressure on slide flooring and sub-structure.
7/8 inch thickness at the securing end provides the right standoff to hold the slide firmly without over-stressing the retraction mechanism.
The Lippert 146364 is a known replacement for Thor Part Number 0246370. If you are sourcing a replacement block for a Thor-built RV with a Lippert slide system, this is the correct part to cross-reference.
The travel block mounts to the underside of the RV floor structure so that when the slide-out is fully retracted, the block contacts and supports the slide room bottom. Verify your existing block dimensions before ordering to confirm the 9 inch width and raised profile match your application. See the product photos for complete dimensional reference.
Lippert produces multiple travel block sizes and profiles for different slide-out configurations. Confirm that your current block is 9 inches wide and uses the raised (elevated) profile before ordering. A standard-profile or different-width block will not support the slide correctly and could cause damage in transit.
