Standoff caps and barrels are components of a standoff system, which is used to mount signs and other media at a fixed distance from a wall or other mounting surface. Standoff barrels are typically made of stainless steel or aluminum and are designed to hold the sign or media at the desired distance from the wall. Standoff caps are attached to the ends of the barrels and serve to hold the sign or media in place.

Together, the caps and barrels create a secure and professional-looking mounting solution for signs and other media. Standoff systems are commonly used in offices, storefronts, museums, and galleries, and are known for their clean, modern appearance. The use of standoff caps and barrels allows for easy installation and removal of signs and other media, making them a convenient and versatile solution for many different types of displays.
