Florida Patio adds 1″ Clear Vinyl lacing to the Chaise Lounge’s support bar. This protects the powder coated finish from the wear and tear of the height adjusting ratchets of the chaise! The clear vinyl is much more resilient to brittleness caused by the sun’s UV rays. This 1″ clear vinyl strap can be easily replaced for next to nothing! Just another example of why Florida Patio makes the World’s Finest Patio Furniture!
