Key Benefits & Features

• Extended Grip Range (20-38 mm): Specifically designed for installation environments with non-standard wall thicknesses, such as triple-layer cladding, thick acoustic insulation boards, or composite hollow structures.

• Reliable Umbrella Clamping: Despite its longer body, the structural steel sleeves collapse into 3 wide-spreading interlocking arms behind the panel, preventing drywall fracture.

• Anti-Rotation Tabs: Sharp teeth beneath the collar bite directly into the front surface of the board, stopping the anchor from spinning while being torqued.

• Application: Ideal for mounting light fixtures onto thick hollow walls, including cable trunks, electrical boxes, security sensors, picture frames, and small decorative elements.
