Torc Ground Anchor - Series II - Technical Details

This page gives various technical details of the manufacture and dimensions of the *Series II* Torc ground anchor. Note that the Series II anchor has been superseded by the Series III design. The details for the Series III anchor are different and are shown on the Series III Technical Details page. We provide this information for the Series II anchor to help customers that purchased the previous product.

Dimensions, Design and Technical Details

The Torc Ground Anchor Series II is compact and unobtrusive when not in use, but large enough to take the largest chains known, including 16mm and 19mm. Most manufacturers would not share information such as follows here. We are happy to share this because we are confident in our design and manufacturing processes and are happy to be compared in fine detail with any other anchor on the market. (Note that the new Series III is better than this!)

  • Shackle: 20mm Diameter Hardened Steel formed as a complete 'D' so two cuts would be required to defeat it
  • Optional: Upgraded 22mm shackle available as a separate item, to support larger chains such as the Protector 22mm Titan.
  • Maximum Vertical Clearance Below Shackle: 68mm
  • Maximum Horizontal Clearance Within Shackle: 100mm (extended semi-circular section with 100mm diameter)
  • Base Plate: 140mm x 94mm overall (shaped by laser within these overall dimensions)
  • Base Plate Thickness: 12mm
  • Base Plate Bridge (i.e. the curved section holding the shackle in position): Cold Drawn Seamless steel, continuously welded on both sides to the base plate
  • Height to top of bridge (highest point, when folded) = 30mm
  • Fitting Area: 140mm x 220mm (overall shackle footprint, allowing folding in both directions)
  • Fixings: Quantity 4, grade 10.9 high tensile M10 socket countersunk bolts, zinc plated, supplied with hardened chrome-steel ball bearings to defeat drilling attempts (quantity 8 fixings for the Block Wall kit - see below)
  • Fixing Hole Centres: At the corners of a rectangle measuring 100mm x 60mm (and another outer set for the Block Wall kit that are on the corners of a larger rectangle measuring 230mm x 160mm)
  • Finish: Zinc phosphate followed by powder coating: Red on the shackle, and Black on the base plate.

Many other anchors have poor quality finishes that will chip and rust prematurely. We have designed the shackle and the base plate on the Torc Series II anchor such that they are unlikely to chip each other in normal use. To provide protection after inevitable chips from the heavy chains expected to be used with this anchor, we have employed a zinc phosphate pretreatment in addition to high grade polyester powder coating - if the powder coating does get chipped, there is still a rust-resistant layer beneath. This is an example of the attention to detail that we give to our products.

Fitting kits for concrete floor/injection resin/brick wall and block wall all include a length of plastic tubing to help you blow dust from the holes. This is very important to achieving a good fixing, whether with chemical resin or with expanding bolts. We also include the correct size of masonry drill bit in those kits, to help you drill the right size hole! Many security products use ball bearings to hammer into the bolt heads. We do the same, but we also include an aid in the kit to help you actually do this as it is not easy otherwise, especially if you are fitting the anchor to a vertical wall! We don't want you to hit your fingers with the hammer! How many other anchors are supplied with such comprehensive contents?

The Torc Ground Anchor is available with a very wide choice of fitting kits to suit your application. We provide the detailed contents of each of the fitting kits.

We claimed for years that the Torc Ground Anchor (Series I) was the best anchor on the market and we had numerous awards and reviews that supported that claim. The Series II is better! The Series III was launched in June 2020 and is better still!
