Dielectric Maxi Overboot

A Class 1 (EN 50321-1:2018) electrically insulating dielectric overboot with a vulcanised rubber sole for superior slip resistance. The Respirex Maxi dielectric overboot is designed to be worn over safety boots and allows live working at up to 7.5kV with every boot tested to 10kV.

  • Ingenious rear entry design ensures the boot is quick and easy to fit and remove over conventional safety boots
  • Slip resistance performance twice that required by SATRA TM144 standards
  • Two to three times the wear resistance of conventional soles
  • Fuel and oil resistant sole
  • Resistance to hot contact 60 seconds 300ºC
  • Meets the requirements of ASTM 1117 (20kV)
  • High VoltageHigh VoltageDielectric boots that comply with the EN50321 standard for electrically insulating footwear.
  • O4 Category Occupational BootO4 Category Occupational BootComplies with the basic requirements for occupational footwear in EN ISO 20347:2012
  • Slip Resistant SRCSlip Resistant SRCTested and approved for resistance to slip on a ceramic tile floor coated with a dilute soap solution of sodium lauryl sulphate (NaLS) [SRA] and Slip resistance on steel floor with glycerol [SRB]. The tests measure forward slip on the heel and with the boot flat to the floor. Boot Marking: SRC
