GEARWRENCH® 891427 Pass-Thru® 27-Piece 6 Point Mechanics Tool Set, 1/4 in Drive, Steel, Polished Chrome, ASME B107.10
The Pass-Thru™ socket and GearRatchet™ ratchet system by GEARWRENCH was designed to improve productivity and access on every job. The GearRatchet™ ratchets need as little as 5° to move fasteners vs. 30° for standard wrenches and are 40% stronger than standard ratchets by eliminating the drive tang. The ratchets are up to 50% thinner than standard ratchets providing superior access to even the most hard to reach fasteners. The Pass-Thru™ sockets are a thin wall design. They replace the need for deep well sockets as they loosen and drive nuts on bolts of any length. The Pass Thru® sockets integrate into the GEARWRENCH GearRatchet™ handle, reducing overall height and increasing torque strength. The GEARWRENCH adapter allows for the use of standard sockets and drive tools.
Littelfuse® POWR-GARD® JLLS350 Current Limiting Fast Acting Fuse, 350 A, 600 V AC/300 V DC, 20/200 kA Interrupt, T Class, Cartridge Body
Space saving Class T fuses are the most compact fuses available in ratings above 30 A - less than one-third the size of comparable Class R fuses. When rated in accordance with the NEC, Class T fuses provide Fast Acting overload and short circuit protection for non-inductive circuits and equipment. Used in inductive circuits, the ampere rating of Class T fuses must be increased to prevent opening on inrush currents. In such instances, Class T fuses may provide only short circuit protection.
