ESD Grounding Drag Chain with 1 Megohm Resistor, Stainless Steel, 610 mm, for Carts and Chairs - Desco 14000

Carts and chairs in the EPA need a constant path to ground without anyone having to remember to plug in a cord. The drag chain trails on the ESD floor and drains charge through a built-in 1 megohm resistor. At 610 mm long with a 152 mm snap loop, it attaches quickly to a frame or chair base.

Key benefits

• Built-in 1 megohm resistor limits current when charge drains
• Chain made of 302 stainless steel, corrosion resistant for continuous floor contact
• Constant ground connection through the ESD floor, no operator action needed
• 152 mm snap loop for tool-free installation on carts, shelving carts or chair bases
• Weighs just 35 g, 610 mm long

Applications

Grounding transport carts, material carts, shelving carts and ESD chairs on dissipative or conductive floors. The chain needs solid contact with the floor. Dust and dirt on the floor, the chain or the worksurface can break the connection, so clean regularly and verify the path to ground from the surface to the floor.

Standards

ESD Handbook ESD TR20.20 lists drag chains as a method for grounding mobile equipment (section 5.3.8) and chairs (section 5.3.5.2) through an ESD floor.
