RIGGING SUPPLY YOU CAN DEPEND ON

Professional Delta Links - Marine Hardware & Rigging

Key Characteristics of Delta Links

• Triangular Shape: Three-sided design with attachment points at each corner
• Multiple Connections: Allows organized attachment of multiple items
• Load Distribution: Distributes forces across multiple points
• Prevents Tangling: Keeps connections organized and separated
• Compact Design: Space-efficient for complex rigging
• High Strength: Rated for significant working loads
• Corrosion Resistant: Stainless steel construction for marine environments
• Versatile Applications: Marine, climbing, rescue, and industrial use

Triangular Design

The three-sided shape provides distinct advantages over traditional single-point connectors.

Design Benefits:

• Three separate attachment points prevent cross-loading
• Connections remain organized and separated
• Forces distributed across the triangle structure
• Compact footprint for complex rigging
• Easy to inspect all connections
• Reduces wear from hardware rubbing together

Stainless Steel Construction

Professional delta links are manufactured from high-quality stainless steel for maximum corrosion resistance and durability.

Material Benefits:

• Excellent corrosion resistance in saltwater environments
• High strength-to-weight ratio
• Durable for long service life
• Maintains strength in harsh conditions
• Easy to inspect for wear or damage
• Professional marine-grade quality

Load Ratings

Delta links are rated for specific working loads and breaking strengths based on size and construction.

Rating Considerations:

• Working Load Limit (WLL) specified by manufacturer
• Breaking strength typically 3-5x working load
• Ratings apply to proper loading configurations
• Various sizes for different load requirements
• Certified for professional applications

Why Use Delta Links?

• Organization: Keeps multiple connections separated and organized
• Prevents Cross-Loading: Each attachment point loads independently
• Reduces Wear: Hardware doesn't rub together causing premature wear
• Easy Inspection: All connections visible and accessible
• Space Efficient: Compact design for complex rigging in limited space
• Load Distribution: Distributes forces across the triangular structure
• Versatility: Works with carabiners, shackles, and various hardware
• Professional Solution: Cleaner, more organized than improvised multi-point connections

Key Considerations

• Load Requirements: Ensure working load limit exceeds your maximum loads
• Size: Large enough to accommodate your hardware (carabiners, shackles)
• Material: Stainless steel for marine and corrosive environments
• Application: Marine, climbing, rescue, or industrial use
• Number of Connections: Verify three points are sufficient for your needs
• Hardware Compatibility: Ensure your carabiners/shackles fit the attachment points
• Certifications: Check for applicable standards if required
• Quality: Choose reputable manufacturers for critical applications

Safe Usage Guidelines

• Proper Loading: Load each attachment point independently, avoid cross-loading
• Working Load Limits: Never exceed rated capacity
• Inspect Before Use: Check for cracks, deformation, or corrosion
• Correct Orientation: Orient delta link to distribute loads properly
• Compatible Hardware: Use appropriately sized carabiners or shackles
• Avoid Shock Loading: Apply loads gradually
• Regular Inspection: Check for wear, especially at attachment points
• Proper Storage: Store in dry location, rinse after saltwater exposure

Critical Safety Warnings

• Load Ratings: Never exceed working load limit on any attachment point
• Proper Hardware: Use only appropriate carabiners or shackles
• Avoid Modifications: Never modify, weld, or alter delta links
• Corrosion Check: Inspect regularly for corrosion in marine environments
• Proper Application: Use only for intended purposes
• Professional Use: Ensure proper training for critical applications

Inspection Guidelines

• Visual Inspection: Check for cracks, deformation, or damage
• Attachment Points: Inspect holes for wear, elongation, or sharp edges
• Corrosion: Look for rust, pitting, or corrosion (especially in marine use)
• Deformation: Check for bending, twisting, or stretching
• Surface Condition: Inspect for scratches, gouges, or damage
• Load Markings: Verify identification and rating markings are legible

Retirement Criteria - Retire Delta Link If:

• Cracks, deformation, or structural damage visible
• Attachment holes are elongated or worn
• Excessive corrosion or pitting present
• Delta link has been shock loaded or overloaded
• Bending or twisting of the triangular structure
• Sharp edges or burrs at attachment points
• Load rating markings are illegible
• Any doubt exists about delta link integrity

Care & Maintenance

• Freshwater Rinse: Rinse with freshwater after saltwater exposure
• Cleaning: Clean with mild soap and water as needed
• Drying: Dry completely before storage
• Storage: Store in cool, dry location away from corrosive materials
• Lubrication: Not typically required for stainless steel delta links
• Documentation: Maintain records for professional applications
• Regular Inspection: Inspect before each use and periodically during storage

What's the difference between a delta link and a rigging plate?

Delta links are triangular with three attachment points, while rigging plates can have various shapes and multiple attachment points (often 4-8 or more). Delta links are more compact and specifically designed for three-point connections. Rigging plates offer more attachment options but are larger. Choose delta links when you need exactly three organized connection points in a compact package.

Can I load all three points of a delta link simultaneously?

Yes, delta links are designed to handle loads on multiple attachment points simultaneously. However, ensure the total load doesn't exceed the delta link's working load limit, and that each individual attachment point is loaded within its capacity. The triangular design distributes forces across the structure when properly loaded.

Are delta links suitable for marine environments?

Yes, when made from marine-grade stainless steel (preferably 316 stainless), delta links are excellent for marine applications. The stainless steel construction resists corrosion from saltwater exposure. Rinse with freshwater after use and inspect regularly for any signs of corrosion, especially in harsh saltwater environments.

How do I know what size delta link I need?

Consider two factors: the working load limit must exceed your maximum expected loads, and the attachment holes must be large enough to accommodate your carabiners or shackles. Measure your hardware and check delta link specifications to ensure compatibility. When in doubt, size up for additional capacity and easier hardware attachment.

Can I use delta links for climbing anchors?

Yes, delta links are commonly used in climbing for equalizing multi-point anchors and organizing gear. Ensure the delta link is rated for climbing loads and made from appropriate materials. Many climbers use delta links to keep anchor connections organized and prevent cross-loading of carabiners. Always use locking carabiners with delta links in climbing applications.
