Universal 4-Hole-Per-Inch Thermal Filament Spines – Bulk Overstock Liquidation

Description: Slash your workbook and document assembly costs to absolute baseline levels. Our 4:1 Pitch 12" Plastic Spiral Binding Coils Clearance features factory-sealed, high-volume overstock boxes priced for immediate warehouse liquidation. Engineered with a precision 4:1 pitch geometry (exactly 4 loops per linear inch), these 12-inch filaments are fully compatible with all standard 11" Letter-format documents bound on manual or electric spiral punching hardware, including systems from Akiles, Rhin-O-Tuff, and GBC.

Manufactured from premium, high-flexibility PVC compounds, these clearance coils will not crack, warp, or turn brittle over time under low-temperature storage or during long-haul freight transit. Featuring an exceptionally smooth external surface finish, these filaments feed effortlessly through automatic coil inserting rollers to maximize your hourly bindery throughput. The 12-inch length provides a mandatory 1-inch clearance overhead on standard 11-inch book blocks, allowing your operators ample material room to execute clean end-crimping locks. This inventory is limited strictly to stock on hand; once these bulk liquidation lots are depleted, these pricing tiers will be permanently retired.
