A slide blind controls flow through conduits at a flanged connection. The slide blind has a right and left working plates configured such that one of the working plates is sealed between the flanges a perimeter thereof adjacent to inner sides of the flange bolts. A joiner member connects the right and left working plates, and handle members extend in right and left directions from the corresponding working plates. The joiner and handle members have a thickness less than the thickness of the right and left working plates. The handle members and the joiner member define first and second sets of bolt holes to fasten the slide blind with either the right or left working plate between the flanges. The joiner and handle members are significantly lighter weight than the working plates, and can be removed for convenient transport.

A conduit apparatus includes a slide plate between faces of flanges connecting a first and second conduit portions. Upper and lower fasteners extend through bolt holes in the flanges above and below the slide plate. Right aid left fasteners extend through bolt holes in the flanges and through bolt holes in the slide plate. The slide plate can be located in a first position where the right and left fasteners extend through a first set of bolt holes in the slide plate and where a first portion of the slide plate is between the faces of the flanges, and in a second position where the right and left fasteners extend through a second set of bolt holes in the slide plate and where a second portion of the slide plate is between the faces of the flanges. The slide plate can be configured to allow or block or restrict flow.

A polish rod clamp apparatus has a body defining a lower rod aperture and a tapered body recess. A cap defines an upper rod aperture and a tapered cap recess. Tapered gripper dies have upper and lower outer surfaces sloping inward from a central portion and inner surfaces configured to bear against the polish rod. The dies are installed in the body recess such that inner surfaces bear against a polish rod and the lower outer surfaces bear against walls of the body recess. The dies are movable with respect to the body and are prevented from rotating. The cap is threaded onto the body such that the upper outer surfaces of the gripper dies bear against the walls of the tapered cap recess. Threading the cap onto the body forces the gripper dies against the outer surface of the polish rod passing through the body.
