Blackburn OD581 COMP TOOL 5/8 DIE STR FBRGLS HNDL

The OD581 is a hand-operated mechanical crimp tool for compressing wire lugs and connectors onto conductors. It uses a 5/8 die and a straight head, so the crimp is made in line with the handles rather than at an offset angle. No power source or hydraulic pump is involved, it is a manual compression tool.

The OD581 is built around a 5/8 die, so the die size is part of the tool as supplied rather than a separate kit selection. It ships as a single tool, sold each, in the one configuration Blackburn lists under model OD581.

Fiberglass handles with a palm grip. The palm grip style lets an electrician put body weight behind the squeeze, which matters when you are crimping lugs overhead or in a panel where you cannot get a two-handed swing on long steel handles.

A manual tool like the OD581 is the right call for occasional lug terminations and service work where you are making a handful of crimps and do not want to haul a pump and head to the job. It is a mechanical crimp tool, so output depends on your hand force. If you are terminating large conductors all day or running a production panel shop, a hydraulic or battery crimper will be less fatiguing. The OD581 covers one die size, 5/8, so match it to the lug your conductor takes before ordering.

Order by the model number, OD581. That designation is the straight-head, 5/8 die, fiberglass palm grip version of the Blackburn compression tool, and the die size is the detail that separates it from the adjacent models in the family. Confirm the die size called for by your lug or connector manufacturer, then match it to the tool.

Country of origin on the Blackburn OD581 compression tool is the United States. For public agency, federal, and institutional buyers working under domestic sourcing requirements, that is the origin on record for this item.
