Hole Products offers a variety of locking plugs designed to provide a watertight, tamper proof seal at the top of monitoring or observations wells. Locking plugs fit the inside diameter of pvc or steel wells. As the wing nut is turned, a gasket seal expands, holding the plugs in place and sealing the well. For vandalism resistance, a standard padlock can be installed. Additional size and styles are available on request. Please contact your Hole Products representative for additional information and ordering assistance.
