• The only supported replacement wire for BN series rebar tying machines - using the manufacturer-specified wire protects machine performance and ensures consistent tie quality
• Approximately 330 ft. of wire per spool - generous length per spool reduces mid-task spool changes and keeps tying pace steady

Why This Product

• Because this is the only manufacturer-supported replacement wire for BN series rebar tying machines, it is the right choice for crews who want to protect tool performance and avoid compatibility issues that can cause misfires or jams.
• With approximately 330 ft. of wire per spool and 50 spools per carton, a single case purchase covers large pours and extended rebar tying work without frequent restocking runs.
• The galvanized 21-gauge construction is specifically designed to work with BN rebar tiers, so wire tension, spool fit, and tie formation stay consistent from the first spool to the last.
