The Showgear Slide 3.0 is a professional mounting system that can be used for a variety of applications. It is a handy accessory for quick and easy repetitive mounting and dismounting of fixtures. It consists of two parts: one part is permanently attached to your fixture and the other part is attached to the mounting surface. Simply slide the part on your fixture into the bracket and it locks into place. The Slide 3.0 is an improved version of the previous model and slides in and out from two sides. Locking and unlocking is quicker and more convenient with a spring-loaded locking mechanism. It is completely rattle free and backwards compatible with the sliding parts of the previous model, so you can easily upgrade your Showgear Slide.
