Product Spotlight

NEW! Innovative Damper Products — We are now offering a new line of Tamco Damper Products constructed with all aluminum extrusions that contribute to prolonged and rust-free operational life. Slip-proof linkage components keep blades aligned. The hexagon design feature of the linkage and pivot elements allows for flat-on-flat press fits, eliminating play and wear. The self-sealing, self-lubricating, and non-absorbent dual bearing system assembly is the secret to long-term and maintenance performance.
