Yellow manhole shield (collar) 12 in high, sturdy polyethylene with inflatable gasket

12 in Manhole Shield — Yellow Polyethylene Collar with Inflatable Gasket

The 12 in high yellow manhole shield is made of sturdy polyethylene and acts as a protective collar around a confined space opening. It is designed to fit 28, 30 or 32 in manholes using an inflatable sealing gasket that fits snugly around the perimeter of the opening. This gasket holds back water and mud from the street up to a height of 12 in, preventing runoff from entering the work space below the surface. The barrier is not included: it is available separately (EPTBB).

This shield is an essential part of preparing a confined space job site or a manhole access. By raising the perimeter of the opening and forming a watertight barrier at its base, it protects the workers below against water and debris infiltration, while clearly marking the location of the opening with its high-visibility yellow color.

Advantages of the EPTBBT Manhole Shield

Protection Against Water and Debris

During work in a manhole or roadside confined space, runoff water and mud can seep into the opening and compromise the safety of the workers below. The inflatable gasket of the EPTBBT creates a watertight barrier that holds back these liquids up to 12 in high, keeping the work space dry and safe.

Versatile Fit

Thanks to its inflatable gasket, a single shield fits the three main manhole diameters (28, 30 and 32 in). There is no need to stock multiple models for the various openings encountered in the field.

High Visibility and Durability

Its bright yellow color clearly marks the location of the opening to pedestrians and vehicles, reducing the risk of accidental falls. The sturdy polyethylene withstands job site conditions and repeated handling.

Use in a Confined Space Context

The EPTBBT shield is part of a complete confined space access setup. It is typically combined with a protective barrier (EPTBB) around the opening, a ventilation system to maintain airflow, and a multigas detector to check the atmosphere before any descent. An appropriate fall protection harness is required for worker entry and exit.

FAQ — EPTBBT Manhole Shield

Is the barrier included with the shield?

No. The barrier is a separate product (EPTBB), available on its own. The EPTBBT shield includes the 12 in yellow collar and its inflatable gasket, but not the peripheral protective barrier.

Which manhole diameters does it fit?

The inflatable gasket allows a fit for 28, 30 or 32 in manholes. This inflatable seal ensures compatibility with the three diameters and the retention of water and mud.

What is the purpose of holding back water and mud?

At the roadside, runoff water and debris can flow into the manhole opening. The shield creates a 12 in high watertight barrier that prevents these liquids from entering the work space, protecting the workers and equipment below.

Complementary Equipment Suggestions for Your Confined Space Access

To fully secure your manhole access, first see the 33 × 33 × 42 in manhole barrier (EPTBB) that surrounds and secures the perimeter of the opening, as well as the passage assembly that maintains airflow at the entry (RA9510). Add the Altair 4X 4-gas detector (DETEC4GC) to validate the atmosphere and the explosion-proof blower kit (RA9548-25EX) for ventilation in a hazardous atmosphere.

Under "Accessories" at the bottom of the page, complete your equipment with the standalone Altair 4X multigas detector (DETEC4G), the Peakworks 6 D-ring confined space harness (FPH2000APLE) and its carry bag (FPBAG).
