An adjustable telescopic cross bar that can be fixed between two walls. Minimum length is 3 feet and max. length is 5 feet. Diameter is not a constraint but should not exceed 3 inches. The outside look should be a simple cylindrical rod. The telescopic extensions from both sides can be manually extended to roughly fit between the walls and then later with the help of some screwing/tightening mechanism the crossbar can be tightly fixed between the walls. The crossbar shall be made of light but strong metal capable of carrying up to 15-20 kg weight.
Hi, I am a product designer in Solidworks and I can design the adjustable telescopic cross bar for you. Just send me a message so that we can discuss more.
