Product Details

The C. Sherman Johnson 27-412 is a closed-body tubular turnbuckle featuring a jaw-to-hand-crimp terminal configuration, purpose-built for marine lifeline applications. Constructed entirely from T-316 stainless steel, this turnbuckle delivers excellent strength and superior corrosion resistance — ideal for both saltwater and freshwater environments.

The streamlined tubular body design keeps a low profile on deck, eliminating the snag points and sharp edges associated with traditional open-body turnbuckles. Check nut locking replaces the need for cotter pins, reducing the risk of lines catching or sails being snagged during sailing operations. The jaw end connects to stanchion bases or other toggle fittings, while the hand crimp terminal end is sized for 3/16" wire and is installed using the Johnson hand crimp tool (models #53-210 or #53-215, sold separately).

Key Features:

  • All T-316 stainless steel construction for excellent strength and corrosion resistance
  • Closed tubular body design — snag-free profile protects sails and lines
  • Check nut locking mechanism — no cotter pins required
  • Jaw to hand crimp terminal configuration for easy field installation
  • 3" adjustment range for precise lifeline tensioning
  • 1/4" jaw pin diameter
  • 1/4"-28 thread specification
  • Compatible with 3/16" wire lifelines
  • Made in the USA by C. Sherman Johnson Co., Inc.

Specifications:

  • Wire Size: 3/16"
  • Pin Size: 1/4"
  • Thread: 1/4"-28
  • Adjustment Range: 3"
  • Material: T-316 Stainless Steel
  • Locking: Check Nut

The C. Sherman Johnson 27-412 is one of the most popular lifeline turnbuckles available and is a proven choice for sailors seeking a clean, reliable, and snag-free rigging solution. Requires Johnson Hand Crimp Tool #53-210 or #53-215 for terminal installation.

As advertised and received the tires within a week. Thank you

I bought my item from them due to the original site I bought from kept telling me my item was back ordered and didnt know when they would have one. It was easy and painless to order and received my item in a timely matter. The price was good especially seeing what other sites were charging, not the lowest price but we'll worth the extra 20 bucks I paid. Will buy from them again if they have what I need.
