High Torque Access Plates

Beckson screw-out access plates made their way in many different operating environments.  The customers loved the durability and watertight seal, but after high pressure conditions the center needed help to be opened.  Beckson designed this high torque center to overcome this problem.  You still have the clarity and toughness of the standard center, but with deeper finger holes and a full pry channel to help sealing and unsealing the unit.

Available in 6" I.D Models.
6" Standard pack = 50 each .
