Base Collar

• The Starter (Base Collar) is the beginning of the
  Ringlock scaffolding system.
• It sits on the top of screw jack creating a lower
  load distribution point.

Standard With Bolted Spigot

• The Standard with Bolted Spigot is the vertical
  member of the Ringlock scaffolding system that
  utilizes a removable spigot. The rosettes are
  placed at fixed increments of 500mm to provide
  vertical support when attaching horizontal
  Ledgers and Diagonal Braces.

Diagonal Brace

• Brace diagonal and/or cross section bracing compon
  ent. Batten or board decking component used to
  make the working platform. Coupler, a fitting
  used to join components together. Scaffold tie,
  used to tie in the scaffold to structures.
  Brackets, used to extend the width of working
  platforms.

Planks

• The Steel Plank is used to form the working
  platform. The number of Steel Planks used
  determines the width of the Bay. The Steel Planks
  span the length of  the bay and hook onto the
  supporting Ledger or Transom. There is an
  anti-lift system(wind latch) to prevent uplift in
  adverse weather conditions.
