Safeguard the inside of your Ikelite DL 8-inch Dome Port for lenses when the port is not in use by placing this Neoprene Rear Cover over it. This soft, gentle piece keeps the port free of dust, dirt, and scratches. Two touch-fastener strips enable you to attach it to the back of the Neoprene Front Cover. Additionally, this rear cover doubles as a convenient, zippered storage pouch for small parts such as spare O-rings, lubricant, and Allen wrenches.
