Storage Battery Systems Inc. has assembled the most popular & necessary tools for preventative maintenance & service repair work on batteries, battery strings & dc power rectifiers. They are completely insulated to prevent voltage related injury to maintenance personnel. Mandatory for all telecommunications central office work, SBS highly suggests the use of these tools on all live dcv circuits. Unlike AC, the battery bus can seldom be completely de-energized making these tools a worthy investment in personnel safety. They are also suited for work on live AC circuit if that must be accomplished. (NEC 2002 prefers not for work to be performed on live AC circuits). The SBS-968 is contained in a durable, flight-ready roller case with stow-away handle & weighs approximatley 40 lbs. with: Low-Voltage Insulated Gloves Size 9 Low-Voltage Insulated Gloves Size 11 12" Insulated Hacksaw 3/8" Drive Insulated Extension Bar (3" long) 3/8" Drive Insulated Extension Bar (6" long) 1/16" Insulated, Long Arm, Hex Key 1/2" Insulated, Long Arm, Hex Key 1/4" Insulated, Long Arm, Hex Key 1/8" Insulated, Long Arm, Hex Key 3/16" Insulated, Long Arm, Hex Key 3/32" Insulated, Long Arm, Hex Key 3/8" Insulated, Long Arm, Hex Key 5/16" Insulated, Long Arm, Hex Key 5/32" Insulated, Long Arm, Hex Key 5/64" Insulated, Long Arm, Hex Key 7/16" Insulated, Long Arm, Hex Key 7/32" Insulated, Long Arm, Hex Key 7/64" Insulated, Long Arm, Hex Key 9/64" Insulated, Long Arm, Hex Key 3/8" Insulated Ratchet Drive 11 pc Insulated Box End Wrench Set (3/8" - 7/8") 3/8" Insulated Socket (5/16") 3/8" Insulated Socket (3/8") 3/8" Insulated Socket (7/16") 3/8" Insulated Socket (9/16") 3/8" Insulated Socket (1/2") 3/8" Insulated Socket (5/8") 3/8" Insulated Socket (11/16") 3/8" Insulated Socket (3/4") 3/8" Insulated Socket (13/16") 3/8" Insulated Socket (7/8") 9/64" X 2" Insulated Slotted Screwdriver Mini Flashlight 1/4" X 6" Insulated Slotted Screwdriver 3/16" X 6" Insulated Slotted Screwdriver 3/16" X 4.5" Insulated Slotted Screwdriver 3/16" X 6" Insulated Nutdriver 1/4" X 6" Insulated Nutdriver 5/16" X 6" Insulated Nutdriver 11/32" X 6" Insulated Nutdriver 3/8" X 6" Insulated Nutdriver 7/16" X 6" Insulated Nutdriver 1/2" X 6" Insulated Nutdriver #2 X 4" Insulated Phillips Screwdriver #2 X 8" Insulated Phillips Screwdriver 7.5" Insulated Diagonal Plier 8" Insulated Needle-Nose Plier 9" Insulated High-Leverage Cable Cutting Plier 9" Insulated Lineman's Plier 10" Insulated Water Pump Plier Insulated Wire Stripper/Crimper 5/16" X 6" Insulated Slotted Screwdriver 3/8" Insulated Tourque Wrench (30" - 150")
