MAIN PIVOT BRACKET, LEFT-4"

Overview

The All-O-Matic 4L-4 is a main pivot angle bracket for the left side, part of the jamb track hardware system used on California Lift Gates. It is welded directly to the gate jamb with its bottom (pivot point to bottom) aligned to the installation reference mark C, and must be set plumb before clamping and welding in place.

Key Features

• Left-side main pivot angle bracket for California Lift Gate jamb track systems
• Pivot point referenced from the bottom of the bracket for precise installation alignment
• Works in conjunction with the main spring bracket — lower holes on the main spring angle bracket are for lighter gates; upper holes are for heavier gates
• Must be installed plumb and level (marks on both sides must be level to allow proper gate balancing)

Specifications

• Side: Left
• Jaw Track Size: 4"
• Installation Reference (Mark C — Bottom of Main Pivot Bracket): 40" (one configuration) / 43" (second configuration) / 43" (third configuration) / 49" (fourth configuration) — refer to Chart 1 for your specific application

Installation Notes

• Align bottom of the 4L-4 with mark C on the jamb as shown in the installation figure
• Clamp and weld with bracket plumb; repeat on both sides
• After installation, bolt the main spring bracket to this pivot angle bracket to complete the spring assembly

The All-O-Matic 4L-4 is a critical structural component of the California Lift Gate jamb track system — correct alignment and welding are essential for safe, balanced gate operation.
