SNB1 29mmø Galvanised Steel Socket with Wing Nuts and Bolts As NO1S with zinc plated wing nuts & bolts. This socket will fit all our platform brooms, and most flat top brooms and prevents the frustration of the handle working loose. The socket takes a 28mm wood pole, and should be used whenever the broom is likely to have regular heavy use. Consider also the STYS2 metal stay. Note that stays are good for wide, open areas but can get in the way when sweeping around congested areas.
