The system, explained
Small footprint. First-line protection.
Trap-It fits within new or existing stormwater pits. Its stainless steel frame, adjustable mounts and staged filtration provide a practical primary treatment option upstream of finer filtration systems.

Purpose in every detail.
Filter in stages
Screens and the filtration bag capture debris and finer material.
Lift out and maintain
The removable insert allows inspection and cleaning; the bypass path remains part of the pit design.
