311-00
Hawle strap - stainless steel

Hawle brackets (stock no. 311-00) are used for the safe installation of tapping and slide clamps on cast iron and steel pipes (see table).

The particularly wide support of 60 mm ensures the lowest surface pressure on the pipe (DIN 3543-2:1984, which has since been withdrawn, provided for a support width of 50 mm for steel and cast iron pipes).

The saddle seal supplied compensates for the respective tube diameter to the tapping clamp and thus reliably seals the drilling.
Note on double stirrup clamps: Two stirrups (retaining pieces) and a special saddle seal are always necessary - please specify when ordering!
