Jam / dance plugs now available in bright colours that will fit most plates. The thread is 5/8 inch standard. When your stoppers start to get in the way, just swap them over for a pair of jam plugs. The high density plastic will make sure the metal of your plate doesn't scratch the floor and will protect your plate from damage too. Jam plugs come as one pair.If you have the bolt on type of toe stop, these will not fit your plate.
