The YORK®STS Connector kits are designed to join the York STS Selectorized units such as the Lat Pulldown, Low Row & Tricep Station to the YORK® STS Cable Crossover and the York STS Functional Cable Crossover. Depending on how you would like to set up your equipment, choose the 4-Way Connector kit to join three additional workout stations to one side (either side) of the Cable Crossover or choose the 3-Way Connector kit to attach two additional workout stations to one side of the Cable Crossover. To add one unit to one side of the Cable Crossover, choose either the 2-Way Adjacent Connector Kit (Stacks positioned side by side) or the 2-Way Opposing Connector Kit (Stacks positioned opposite each other). Available in three colors, these connector kits require little assembly and hold the units securely in place creating a dynamic commercial grade Multi-Station.
