From time to time I get asked the question, “can I use the barbell sliders to convert my rack into a Smith machine”? My answer to this is, “as long as your rack has 50mm x 50mm (2″ x 2”) square uprights that are no more than one metre apart (inside measurement) then, yes you can. You will need to drill holes in the uprights and maybe make a pair of safety stops“. Detailed step-by-step instructions on how to build the sliders and safety stops can be found in the HGB build manual.
Can you buy the sliders ready-made?
Well, the short answer is yes. I can build you a pair, but they are not going to be cheap. That’s one reason I offer plans to build your own. If you want me to build them for you, then they will cost £450 for the pair, plus shipping.
