Blum TANDEMBOX Antaro Top-Mounted Stabilisation Set – ZST450BA

Help wider drawers run smoothly and reduce racking, the unwanted side-to-side movement that can occur during opening and closing. The Blum ZST.450BA top-mounted side stabilisation set adds lateral stability to compatible TANDEMBOX drawer installations with a 450mm nominal length.

Used alongside the drawer runner system, the stabiliser helps a wider drawer move more evenly. Its aluminium linking rod is easy to cut down to suit the cabinet width, making it practical to adapt the set to the installation rather than treating the stated 450mm nominal length as a fixed cross-cabinet bar length.

Choosing and fitting the stabiliser

Match the ZST.450BA reference to the drawer system and 450mm nominal length. The 450mm designation is not the finished transverse rod length. For this top-mounted system, Blum specifies the rod cutting length as internal cabinet width minus 86mm. Measure the cabinet and follow the assembly instructions before cutting or drilling.

Side stabilisation complements the runners; it is not a replacement runner or a lock-open mechanism. It is particularly useful on wider drawers where additional control of side-to-side movement is needed. Check the exact system and mounting clearances rather than assuming all TANDEM, TANDEMBOX and MOVENTO stabilisers are interchangeable.
