Helix Anchors

helix anchor Helix Anchors (complete sets)
  • Both the 1-3/4 in. & 1-1/2 in. square shaft anchors sold as complete units (lead sections & mooring terminations w/shackles)
  • Lead sections come with a variety of different helix combinations
  • Number and size of helices depend on the substrate
lead sections Lead Sections (only)
  • Lead sections come with a few different combinations of helices and lengths
  • Hard substrates typically use smaller and fewer helices, while softer soils require more, and sometimes larger, helices
  • Hard rubble coral areas typically use a lead section with a 8"-10"diameter helix and cutting teeth
  • Softer sandy sections of the reef or mooring area call for a lead section with 8, 10, or 12 in. diameter or larger helices

mooring head Mooring Head
  • 1-1/8 in. shackle will pivot around the shaft as the vessel moves, eliminating the need for a swivel in the ground tackle
  • Shackle pivots around the entire shaft of the anchor, offering much longer life
  • Available in different lengths, 18 in., 3 ft., 5 ft.
extensions Extensions
  • Used to add length to the anchor, so the helices can penetrate further into the substrate to achieve greater holding
  • Drop-forged box connections, with 1 1/4" fastening bolt
  • High grade galvanized steel
  • Variety of lengths 3 ft., 5 ft., 7 ft., 10 ft.
Timber Bracket Timber Bracket:

These brackets are used to connect timber beams to helical piles. The split bracket design is more universal because variability in timber beam thickness does not pose a construction problem. Both of these brackets fit over an SS5.

  1. C110-0682 bracket has an ultimate rating of 10,000 lb in compression.
  2. C110-0736 is designed to attach to battered piles for lateral support.

Standard finish is Hot Dipped Galvanized per ASTM A153. For different size shafts, mounting holes, or special finishes please contact us.
