Height Restriction Barriers - Sentinel Goalposts

Our height restriction barriers whilst being new to the North American marketplace are already saving lives throughout the continent. They can be deployed quickly to prevent tall plant equipment hitting overhead power lines, they can also be used to indicate if a vehicle is too tall to pass under a bridge or similar obstruction. All in all these height restriction barriers are a safety game changer that can save thousands in fines and costly repairs.

Sentinel Goalposts Height Warning Barrier Kits

Our Non-Conductive Height Warning Goalpost Barrier system is a lightweight, cost-effective solution to aid on-site safety by warning users of overhead dangers. Use our kits in accordance with OSHA & INGAA guidelines as well as other construction safety standards. This system is designed to be set up by bridging an access pathway before and after an overhead obstacle which should be avoided.

Engineering and construction groups require multiple levels of safety control, one of which is a physical warning barrier to prevent contact with overhead structures or obstacles. In the past, many make-shift warning devices have been used to warn personnel and vehicles about overhead obstacles such as power lines and building structures, but our kits offer improved safety and fast adjustable deployment. Ensure your team has adequate protection with the Sentinel Goalpost kits.

Our kits are also known as GS6 goalpost kits, guardian goalposts, overhead goalposts, safety bunting/flagging warnings, non-conductive height warnings, overhead collision warning systems, and overhead cable protection posts.

Each kit includes a choice of two bases, 2 telescopic non-conductive upright poles, and 82ft of flagging/bunting. Most users decide to use the water-fillable Metro Bases for independent stability.

Only use in accordance with your local state guidelines and OSHA standards

OSHA 1926.1408 - Power line safety equipment operations.

Always determine your MAD (Minimum Approach Distance) to setting up your flags or range limit/range control warning devices. See below for more resources and refer to our Download section for our product setup guide before installation.

Water Fillable Metro Ballast Base for Sentinel Goalposts

Base Options

Water Fill Metro Ballast Base

The new plastic ballast base is the best option for short to medium timeframes as there are no fixtures or fittings needed by filling the Metro ballast base with 27 gallons of water to yield 242 lbs in weight for heavy stability. Constructed from polyethylene, it is extremely resilient and allows for continual use in harsh environments. Each unit is water tested in production before despatch.

Fixed Galvanized Steel Base

If you require a fixed long-term solution in multiple places and only move the Telescopic Poles for the project location you're working on. The base has four 1/4" mounting holes to anchor the base in position. Please note: you must always fix this base down through the 4 accessible holes before use.

Contact Options

Flagging (Bunting)

All kits come with our reliable 82ft length of flagging.

This restriction method comes in red and white color as standard, they are highly visible to anyone at a distance. The flagging copes impressively well in many conditions.

Sentinel Goalpost Bunting/Ribbon Bundled

Crossbar

The crossbar is the most secure method of overhead height restriction.

In harsher weather conditions, the crossbar can be more effective than flagging with more positive confirmation on contact. The pole is made from fiberglass, and functions in the same way our standard telescopic poles do.
