Security Locking Standoffs - We introduced a new series of panel and sign standoff supports with tamper proof security feature. These items provide fast, safe and easy installation just like our regular through standoffs. The locking set screw on the base of the spacer provides an excellent way to secure the front caps, therefore locking the panel in place. They are ideal for mounting glass shelves and countertops, display panels and screens, signage, logo panels, photographic frames, decorative structural elements, etc. They are machined using only high-grade brass with quality chrome plating. They are available in 20mm (3/4") and 25mm (1") diameters with barrel length of 25mm (1"). Custom sizes or finishes are also available; 500 pieces minimum and an up charge may apply. Call for pricing.
