## Summary description

Straight coupler for protective (shielding/oversheath) lightning conductors, model ZGROM 28 by TTPLAST (MPN 10788, EAN 5908312755647). Designed to join or extend protective conduit sections with a nominal size indicated by '28'. Used in lightning protection and earthing installations to ensure continuous mechanical protection of conductor runs. Suitable for outdoor and building roofline applications where secure conduit coupling is required.

## Long description

The Protective Conduit Straight Coupler TTPLAST ZGROM 28 is a rigid inline connector designed to join or extend protective conduit sections used in lightning protection and earthing systems. It provides mechanical continuity for oversheath or shielding conduits, maintaining a continuous protective cover around conductor runs on building exteriors and rooflines. The coupling is sized for conduits with a nominal diameter of 28 and is intended for installations where a secure, weather-resistant joint is required.
Advantages
The straight coupler delivers a precise fit and stable mechanical connection between adjacent conduit lengths, reducing the risk of exposure or displacement of the protective sheath. Constructed to withstand outdoor conditions, it supports continuous protection along conductor runs and simplifies alignment of conduit sections during installation. Its simple inline design allows for efficient extension of conduit paths while keeping the protective function intact.
Suitable for
 Lightning protection systems on building roofs and façades
 Earthing conductor protective coverings
 Outdoor conduit routing where mechanical protection is required
 Extension and repair of existing oversheath conduit runs
Key specifications
 Type: straight inline coupler for protective conduit
 Nominal conduit size: 28 (for conduits with corresponding internal/external diameter)
 Function: mechanical joining and continuous oversheath protection of conductors
 Typical application environment: outdoor/roofline and façade installations
 Installation: push-fit or slip-on joint designed for secure alignment of conduit sections
How to use
Align the conduit ends to be joined so that their axes are colinear, then slide each conduit end into the coupler until fully seated. Ensure the conduit sheaths overlap inside the coupler to maintain continuous coverage of the conductor. Verify alignment and mechanical seating visually and by a gentle pull test. Where required by installation standards, secure the joint with appropriate clamps or fasteners and apply corrosion-resistant sealant or tape for prolonged outdoor exposure.
Usage recommendations
Use the coupler only with compatible conduit dimensions and materials; confirm fit before permanent installation. Follow local electrical and lightning protection standards for spacing, supports, and grounding continuity. Inspect joints periodically for mechanical integrity and weather-related wear.
