The HyDrain 2nd Fix consists of a domed grate with a flange that is held together by 4 x bolts & nuts.

This product acts as a full-bore and is a suitable replacement to the common cast iron full-bore that has traditionally been installed on flat concrete roofs to drain rainwater.

The HyDrain 2nd Fix can be installed either in conjunction with or without it's 1st Fix counterpart.
