Replacement Bimini Top Canvas for Square Tube Pontoon Biminis with 4 Bows

Replacing your Bimini tops worn out fabric can be a hassle. Unless you know who made the top originally, it's sometimes hard to ensure that another manufacturers canvas will fit your existing frame. Even if you know the manufacturer of the Bimini, many times they may be out of business.

Carver Industries has taken the guess work out of it, and they've made it easy to get a new canvas for your pontoon Bimini top frame! Their replacement canvas is a special product which is made with larger sleeves for the bows to ensure that it will fit nicely onto your frame. Unlike other replacement canvases (which are usually more generic), it won't fit sloppily, and it will stay securely in place.

More About Carver's Replacement Canvases

Carver uses the same features on this product that they do on their custom made bimini top canvases. With some canvases, you have to remove your frame from the boat to install them. This one has zippered sleeves so it goes on easily and quickly. It comes off just as smoothly, so you can pack it up for storage when you aren't using the boat. The canvas also has a cut out for a running light.

This replacement canvas is made to fit a large variety of manufacturer's 4 bow square tube pontoon bimini top frames. We offer the replacement fabric in lengths of 8, 9, or 10'. Canvases are offered in various materials and colors to choose from, each finished with black trim. To measure your existing bimini and determine which size you need, put your frame in the open position, and measure the length of the frame from the front of the front bow to the back of the back bow. This canvas is made to fit on a frame with a tubing diameter of either 1 or 1.25". It's made for a bimini that mounts at widths of up to 102”, and for a height of 48".
