pull up bar Hi, i'm making a pull up bar and wanted to use these to anchor the steel bar to the wall. How many holes are there in the plate to secure it to the wall? and do you think it will take my weight (10st) if the bar is approx 1.3m in length? Existing Answers Hello, there are 4x holes in each clamp, and yes it should be fine for a pull up bar, we have done a lot of them!
