Product Introduction

The system uses a rectangular stainless transit frame packed with fitted red elastomer modules around three individual black cables. Four corner bolts retain the frame while the modular grid fills unused opening area and provides defined service passages.

Key Features

Individual modules organize separate cable routes.

A rigid stainless frame protects the penetration perimeter.

Replaceable blocks support compatible service changes.

Four-point mounting provides accessible retention.

Customer Product Concerns

Mixed cable bundles leave irregular voids that are difficult to close consistently and inspect.

Loose cable bundles create uncontrolled gaps.Fitted modules close space around each cable.

Raw openings expose rough partition edges.The stainless frame defines and protects the perimeter.

Permanent filler complicates cable changes.Compatible modules can be removed and rearranged.

Uneven packing leaves local weak points.A complete modular grid provides repeatable filling.

Typical Applications

Cleanroom cable transitsControl-room service openingsElectrical room boundariesUtility-panel penetrations
