You can find many pull-up bars for a lower price, but our bar offers more: it is in fact compatible with all the accessories of the Royal series, which are usually fixed on the profiles of the rigs. Therefore, you can mount the cannonball grips, the multi-grip bar and much more.This product went through the galvanization process, and can therefore be used also for outdoors. Galvanization is a special process that prevents the steel to rust, when exposed to humidity.The accessories are not galvanized and therefore cannot be left outside but must be stored indoor to prevent rusting.The package also includes all the bolts needed to assemble the product (excluding those for wall mounting).
