Fork Extensions - Star Industries

📘 Overview

Star Industries Fork Extensions slip onto existing forklift forks to extend reach for bulky and oversized loads. Available in three widths: Model 1664 (for 4" × 48" forks, 72" OAL, 120 lbs/set), Model 1665 (for 5" × 48" forks, 72" OAL, 140 lbs/set), and Model 1666 (for 6" × 48" forks, 72" OAL, 160 lbs/set). Install and remove in seconds with the locking pin. Important: extension OAL must not exceed 150% of existing fork length; inside width must not exceed 1/2" wider than the fork. 5-year factory guarantee. USA since 1981.

🔑 Benefits

• Extends fork reach for oversized and non-standard loads without replacing forks or buying a longer fork set — large machinery, equipment bundled on long pallets, and oversized structural members require more than standard 48" fork depth to pick up safely. Extensions add the required depth instantly without purchasing or storing a dedicated set of longer forks.
• Seconds-long installation means forks can be extended per-load without workflow interruption — bolted or welded fork extensions require tools and significant setup time. Slip-on extensions with locking pins install in the time it takes to position them and insert the pin — operators can add or remove them between loads with no tools and no disruption to loading operations.
• Three fork widths (4", 5", 6") ensure a proper fit without side play that causes load shifting — using an extension wider than the fork by more than 1/2" creates gap-induced side-to-side movement under load. Star's three-width range allows exact matching to the most common fork widths, eliminating the rocking and shifting that cause load drops with ill-fitting extensions.
• Locking pin retention prevents extension slippage under dynamic loads — some fork extension designs rely only on fork taper contact to retain the extension. The locking pin positively retains the extension on the fork during dynamic acceleration, cornering, and uneven ground conditions where inertial forces could otherwise slide an unretained extension forward off the fork tip.

📊 Specifications

🔗 Attachment Compatibility

Forklift capacity is substantially reduced when the load center moves beyond the standard 24" load center. Consult your forklift's load capacity chart at the extended load center before picking any load with fork extensions installed. Match extension width to existing fork width — inside width must not exceed fork width + 1/2".

🚜 Machine Compatibility

Compatible with forklifts and telehandlers — slides onto standard fork tines:

Extensions reduce forklift capacity when load center exceeds 24". Consult machine load capacity chart before any lift with extensions installed.
