Heyco Dome and Vent Plugs close unneeded panel holes and electrical knockouts, offering quick and easy installation. The plugs feature a convex, matte finish head with an approximate 1.6mm (0.062") thickness that tapers to a thin edge with locking fingers in fractional increments up to the maximum panel thickness [6.4mm (0.250")]. The Heyco Dome and Vent Plugs offer a UL 94V-2 flammability rating and -40°C to +105°C temperature range. The Vent plugs additionally permit the passage of air for ventilation and heat dissipation.
