Placement: It is positioned at the top of the base plate, screw jack, or swivel jack to initiate the scaffolding erection.

วัสดุ: Usually made from high-strength, low-alloy structural steel.

Surface Treatment: Commonly hot-dip galvanized for corrosion resistance.

Sizes: Standard sizes include 240mm, 280mm, 300mm, 330mm, and 430mm, with custom sizes available.

Weight: Varies by size, but standard base collars typically weigh between 1.45 kg and 2.34 kg.

Standards: Manufactured to meet various standards such as EN 12810, AS1576, and ANSI.

Function: Provides a level and secure base for the scaffolding, aiding in the stability of the entire structure.
