MIXING NOZZLES For the Sympafix line of chemical anchors special designed mixing nozzles are available. The nozzles are designed to ensure proper mixing and to safeguard quick and correct extrusion. Each cartridge size in the extreme, concrete and multibase lines use specific mixing nozzles. For deeper rebar applications nozzle extensions are available. PLASTIC AND STEEL MESH SLEEVES For using Sympafix chemical anchors in brickwork and hollow material, specific designed plastic and metal sleeves are available that ensure proper installation. The chemical anchor that protrudes through the holes forms a good grip on the base material. The plastic sleeves have a fixed length, and the one meter metal sleeves cut to the required length.
