Mod Rails

Mod Rails Meet the Mod Rail—your new modular powerhouse for obstacle setups! Designed to be both a stand-alone challenge and a versatile anchor point, the Bookend can hold a wide variety of attachments and mount in multiple orientations. Use it as the final piece in a lane, the start of a new challenge, or a creative connector between obstacles. With multiple T-nuts and mounting options, you can attach holds, rings, pegs, ropes, or straps—your course, your rules. Whether you're building a kids’ line or a pro-level route, the Mod Rail makes it easy to mix things up and keep training fresh.  These can be mounted on to existing trussing, ModTruss Set-ups, as well as just into wood. 🪵 Handcrafted from durable birch and finished for long-lasting indoor use. Expand your ninja setup with the fully modular Silent Kninja system! Included: 1 x Mod Rail (45" x 4"), 1 x Set of Two Bookends (6" x 8") with 0 degree, 5 degree, or 10 degree angle. Additional Bookends can be purchased separately - See
