These Hardtop Stands allow convenient vertical storage of your precious convertible hardtop. Our design includes a securing harness, which provides stability while maneuvering the hardtop on its storage cart. Supplied with double-wheel, lockable castors and support padding, these carts work exceptionally well with heavy hardtops and are an ideal storage solution. The complimentary cover is a generic fit sized to cover your hardtop on its storage cart. This large-sized cover fits the larger tops including the BMW 3 Series, Mercedes, Cadillac Allante and Thunderbird hardtops. If you own a smaller hardtop, our regular cover and cart package will be better suited. Please note self-assembly of the stand is required. Hardtop not included!

We're here to help. This stand is NOT compatible with the TRIUMPH TR6, as there is not enough ground clearance on this stand to accommodate the "winged" part of the hardtop. Our cart with 5” diameter castors will suit these hardtops. Please note this stand is NOT compatible with the Wrangler or Gladiator hardtops. These tops are a significantly different shape and size to a sports car hardtop.
