TLW-RB Suspension

Low Profile. Fast Adjustments. Full Control.

The TL-Series is the lowest-profile suspension in the lineup, offering a compact and highly responsive seating solution for high-performance marine environments. Designed with a quick-access handwheel for instant weight adjustment, it’s perfect for skippers who need on-the-go adaptability with zero hassle.

Despite its slim height, the TL-Series packs a punch—delivering full swivel and slide functionality and offering the same reliable shock protection and marine-grade durability you expect from 4S.
