Royer's 2 piece Aluminum locking monitoring well caps are for use in securing above ground protective risers on monitoring well locations. The bottom half of the cap secures to the riser casing with Allen head screws. The top half slides over the bottom flange covering the Allen screws and making them un-accessible. With the top half over the bottom, they can have a padlock installed to secure the well. These locking well caps are not water tight.

NOTE:  These are for monitoring wells. They are not for water wells with a submersible pump installed in the well. These caps do not provide a port for bringing pump wire out through.

Lockable Monitoring Well "J" Plugs

418XA

These Limited Access Environmental Manholes are offered in 8", 12", and 18" sizes, feature a clearly marked "Monitoring Well" designation which distinguishes them from a standard product fill manhole. These monitoring manholes feature a heavy duty cast iron cover and ring, a fuel resistant gasket to make them watertight, and a heavy galvanized steel skirt to maintain an open area below the lid to work. Two stainless steel bolts are used to secure the lid, limiting access to the monitoring well below. These manholes are traffic rated at 8,000 lbs per tire and conform to H-20 ratings.
