JG Speedfit pipe clip & spacer is used to fix pipe to timber when running concealed pipe work. This option uses a screw to secure in place. When pipes are required to cross over, a pipe spacer can be added to the clip. If pipework needs to be insulated, the spacer will give room for any lagging to be applied.
