Our SS1919 are panel and sign standoff supports with a 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 counter-tops, display panels and screens, signage, logo panels, photographic frames, decorative structural elements, etc. They are machined using only high-grade stainless steel in a brushed finish.
