A11 Staple Hammer, made by Tacwise, this tool is a must for all carpet fitters, takes 8mm-10mm /140 staples. This A11 staple hammer is a very rebust tool, which should be lightly oiled from time to time, with a light machine oil (3 in one oil) something carpet fitters forget! You should not overload staples into the staple hammer as this will cause it to jam. Used to fasten the underlay to the floor, the A11 staple hammer tool is the fastest and most practical way to ensure the underlay does not move under the carpet. However, for under steps and bull nosings the electric stapler is the best tool.(see RWS113) (Please note:- this staple hammer comes without staples these can be purchased separately see product code RWS018 for 8mm staples.) Replacement pusher rods are available for this A11 staple hammer code no RWS033A
