I recently purchased an adjustable handle from the handles & pulls section of the Industrial and Scientific hardware section. As my tests showed, the thread mechanism FUNCTIONS smoothly and the orange color gives it a unique edge. The handle is made from durable materials and is capable of handling heavy loads. The only downside is the price, which appears to be slightly higher than similar handles on the market .Overall, I am highly satisfied with the quality of this handle and recommend it to other industrial hardware enthusiasts..
