The GS6 is a telescopic height restriction barrier system designed for Traffic Management and road barrier applications on Construction Sites, Infrastructure Projects, and any location where overhead hazards present a risk to vehicles and plant. Adjustable from a minimum height of 1.83m to a maximum of 7.53m via telescopic poles and quick-release hand-operated clamps, the GS6 is positioned at the approach to restricted zones to alert drivers before they reach overhead powerlines, scaffolding, temporary structures, or other hazardous overhead obstacles.
The GS6 is manufactured from Glass Reinforced Plastic (GRP), a non-conducting material. This is a critical specification requirement for height restriction systems deployed near live electrical infrastructure, where a metal frame creates a conductivity risk. The non-conducting GRP construction addresses the safety compliance requirement for work near overhead powerlines and high-voltage cables without additional insulation or engineering controls.
One person assembles the GS6 without tools. Quick-release hand-operated clamps adjust the telescopic poles to the required clearance height and lock securely in position. Two base options are available to suit different site conditions: metal bases at 55kg for stable, permanent-feeling deployments, and water-filled blocks at 10kg for sites where portability and lightweight handling are priorities. Red and white pole sections provide clear visual identification from the driver's approach line.
Key Features and Benefits
Adjustable from 1.83m to 7.53m: Telescopic pole system covers the full range of overhead hazard heights encountered on UK construction sites and infrastructure projects
Non-conducting GRP construction: Eliminates conductivity risk near overhead powerlines and electrical infrastructure, meeting the safety compliance requirement for height restriction systems near utilities
Single-person, tool-free assembly: Quick-release hand-operated clamps allow one operative to set up, adjust, and relocate the system without additional tools or labour
Two base options: Metal bases (55kg) for stable deployments; water-filled blocks (10kg) for portability and lightweight site logistics
Red and white pole sections: High-visibility colouring provides clear driver identification from the approach line
Compatible with road barrier layouts: Integrates with existing traffic management and road barrier configurations on construction sites
Frequently Asked Questions
Q. What height range does the GS6 cover?
A. The GS6 height restriction barrier adjusts from a minimum of 1.83m to a maximum of 7.53m via telescopic poles and quick-release hand-operated clamps. Two base types are available. Metal bases weigh 55kg and are suited to sites where stability and permanence are priorities. Water-filled blocks weigh 10kg, making them the better choice for sites where portability and frequent repositioning are required. The base choice should reflect the site conditions, ground surface, and how often the system will need to be relocated during the project.
Q. Why is the GS6 made from GRP (Glass Reinforced Plastic)?
A. GRP is a non-conducting material, which means the GS6 frame does not transmit electrical current on contact with overhead powerlines or other live electrical infrastructure. This is a safety compliance requirement for height restriction systems deployed near utilities on construction sites. A metal frame in the same position creates a conductivity risk that would require additional controls or would preclude use near live electrical overhead hazards. GRP removes that risk by design, making the GS6 the appropriate specification for sites where overhead powerlines, high-voltage cables, or electrical structures are present within the working zone.
Q. Can one person assemble the GS6 height restriction barrier?
A. Yes. The GS6 assembles without tools and is designed for single-person setup. Quick-release hand-operated clamps adjust the telescopic poles to the required clearance height and lock in position without specialist equipment. For traffic management and road barrier applications on construction sites, this means the system is deployed and adjusted by the site operative on the ground without the need for additional labour. The red and white pole sections are visible from the driver's approach line, providing a clear warning before vehicles reach the restricted overhead zone.
