The coupler may also include a coupler body including a first end, a second end, and a passageway extending between the first end and the second end, the first end secured to the first chuck, the second end secured to the second chuck, the first end including first internal threads engaging the first external threads, the second end including second internal threads engaging the second external threads.

Intermediate coupler for concrete reinforcement

A cover is provided for sealing a concrete anchor including a flange and a bore extending through the flange. The bore defines an axis and the flange has a first side and a second side. The cover includes a first cover portion for covering a portion of the anchor proximate the first side of the flange, a second cover portion for covering a portion of the anchor proximate the second side of the flange, and a latch coupling the first cover portion and the second cover portion together with the anchor disposed between the latch.

Sealing cover for concrete anchor

Methods and devices for sealing and/or gripping concrete strengthening tendons. Some embodiments provide a method of forming a seal between an encapsulated anchor and a sheath of a tendon engaging the encapsulated anchor. Other embodiments provide a splice for forming a seal around a discontinuity in the sheath of a concrete tensioning tendon. Some embodiments provide a seal assembly for forming a seal between a tubular extension and a sheath of a tendon to protect an exposed portion of the tendon contained within the tubular extension. Some embodiments also provide a method of forming a fluid tight seal between tubular extension and a sheath of a tendon, while other embodiments provide a method of gripping the sheath of a tendon with a tubular extension to prevent the sheath from moving relative to the extension.
