HEX Polymer Earth Pit Chambers – Square & Round, Load Bearing up to 5 Tonnes

HEX polymer earth pit chambers house and protect the top of an earth electrode so it can be inspected and tested. They are moulded from customised high-density polymers for strength and resistance to high stress, stabilised against degradation from all weather conditions, and made in a wide range of sizes and colours. Being light, they are easy to handle, store and transport, and most lids have a locking arrangement for built-in safety. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).

At a glance

• Material: customised high-density polymer, UV and weather stabilised
• Shapes: square and round
• Load-bearing capacity: 3 to 5 tonnes, depending on model
• Lids: polymer, or metal cover (HEP-M); most with locking arrangement
• Weight: 0.75 to 5 kg
• Tested: load-bearing capacity to IEC 62561-5 (TCR Engineering Services) on HEP and HEPR-A

Why choose HEX polymer pits

• Strong but light — up to 5 tonnes load-bearing, yet a 308 mm square chamber weighs only 2.5 kg.
• Weatherproof — stabilised against degradation in sun and rain.
• Safer — most lids lock, keeping the test point secure.
• Choice of sizes and colours, square or round, polymer or metal cover.

Polymer or concrete pit?

• Polymer (this page) — light (0.75–5 kg), lockable, easy to carry to site; 3–5 t load bearing.
• Concrete — heavy (25–130 kg) ready-made chambers for sites that want a solid, fixed housing; 3–5 t load bearing.

Frequently asked questions

How much load can a HEX polymer earth pit take?

HEP, HEP-M, HEPR and HEPR-A are rated at 5 tonnes; HEP-S, HEP-A and HEP-B at 3 tonnes.

Do the lids lock?

Most HEX polymer lids have a locking arrangement, giving the earth pit an in-built safety feature.

Will a plastic cover last outdoors?

Yes — the polymers are stabilised against degradation and damage from all weather conditions.

Which size should I choose?

HEP (308 mm square) is the common general-purpose size; HEP-A and HEP-B (500 mm) give more room for several connections; HEPR and HEPR-A are round covers.
