The Standard Dildo System consists of a welded steel platform arm and retaining strap. This strap is sewn from Velcro and webbing. This dildo system works well with most dildos that have a wide or flared base, particularly ones with balls. Also available, and sold separately, is the Vac-U-Lock Dildo System (link below). This machined aluminum plug matches the shape used with Vac-U-Lock dildos. This system does require Vac-U-Lock dildos. Note: Dildos are not included. Which Dildo System is right for you? This depends primarily on the type of dildos you own (or plan to purchase). If you do not own dildos presently, we highly recommend the Vac-U-Lock system. It is easier to use and extremely secure. Obviously, the most flexible solution is to own both dildo systems. Extra Available Options: , Black Magic 14 Inch Extension Arm, Dildo Doubler, Vac-U-Lock Fucking Machine Adapter.
