Use the C.S. Osborne W-1 Hand Press to set 1" vent grommets, sometimes known as ventilators, using this die set. Add vent grommets to cushions, boat covers and more to add airflow and prevent the moisture buildup that causes mold and mildew to grow.

This set contains three dies that both cut the hole and set your vent grommets. The cutting die is installed in the top of the W-1 Hand Press and works in conjunction with the nylon cutting block that was included with the tool. After a hole is punched, install the two setting dies into the tool to set the vent grommets.

Please note: This set contains the dies only. The W-1 Hand Press is sold separately.

Note: This die is also compatible with the Sailrite® HandyPress® (#125401).
