Description
The HDMount 55 mm Square Plate (1″ Ball) provides a solid, low-profile interface for mounting in-cab equipment across commercial transport, agriculture, material handling, and industrial fleet vehicles. Featuring a flat 55 mm × 55 mm square footprint, it functions either as a permanent flat-surface base (bolted or screwed to dashboards, consoles, or bulkheads) or as a rear mounting adapter for compatible electronic brackets and cradles.
Engineered for broad mounting compatibility, the plate incorporates a standard 40 × 40 mm square 4-hole screw pattern alongside two elongated slots/holes, allowing for flexible bolt alignment and fine positional adjustments. Centred on the plate is an industry-standard 1″ (B-size) rubberised ball that dampens high-frequency vehicle vibrations. When connected to any modular 1″ dual-socket extension arm, it enables full 360-degree rotation and broad tilt articulation to achieve the optimal viewing angle.
