Instalocks are the next evolution of the already popular and effective Cam and Groove Fitting. Instalocks are designed to be even easier to use, and don't require pins! The unique Instalock design uses special self-locking arms that hold themselves in place until you manually unlatch them.
Instalocks are easy to use in the cold too! Unlatching an Instalock is so easy, it can be done with gloved hands in cold weather. Instalocks come in multiple materials, including Aluminum, Brass, and Stainless Steel.
