Alvin Industrial Lockinex™ Streamlined tube connectors are the most effective and convenient method for butt joining tubular railings of the same diameter.

These internal expansion connectors have been engineered so that they give the perfect non-slip joint that is completely flush and virtually unnoticeable. Available in single screw or double size for heavy duty applications. Their unique design enables them to be inserted into the tube without the two halves separating.

Once the allen screw(s) has been tightened the Lockinex™ Streamlined tube connector contacts the tube internally in four areas along the full length. This ensures alignment and maximum strength. Lockinex™ Streamlined tube connectors can only be used to join the same size tubing.
