You need the following to assemble: Rubber mallet. Before you start: Mount the hang standards. Step 1: Identify which storage track fitting is left vs. right. The left fitting has an L-shaped tab pointing to the right when the smooth long side is facing you, and the small tab with a hole is pointing upwards. Step 2: Push the left and right fittings into the storage track. Use a rubber mallet if needed. Step 3: Assemble the storage track into the inner slots of the hang standard, by leaning the storage track slightly upwards, so that the upper "teeth" can be inserted into the designated slots. The lower teeth will then fit in easily, when lowering down the storage track. Step 4 (depending on load): Secure the storage track with screws. Track with Track Fittings in a W: 60 section * Load <10kgs = no need to secure with screw * Load >10kgs = minimum 1 screw positioned in the middle Track with Track Fittings in a W: 90 section Load <10kgs = minimum 1 screw positioned in the middle Load >10kgs = minimum 2 screws positioned in the 2 center screw holes It is not recommended to use Track Fittings in sections wider than W: 90 (>900 mm). Important that no Hooks be positioned over the cut out due to safety.
