Lattice – Triple Rung – Wooden Hangboard for Finger Strength Training

The Triple Rung from Lattice Training is one of the most recognised hangboards for finger strength testing and structured training. With its minimalist design and carefully engineered edge geometry, it provides reliable, repeatable loading for climbers looking to measure and develop finger strength.

Designed with input from coaches, athletes and sports scientists, the Triple Rung focuses on three essential edge sizes, allowing climbers to warm up, train, and test their finger strength using a single, streamlined board.

Three Edges for Complete Finger Training

The board features three key edge depths designed to cover the most common training needs:

• 45 mm edge – ideal for warm-ups and progressive loading
• 20 mm edge – the industry benchmark for finger strength testing and training
• 10 mm edge – for developing strength on small edges

This simple configuration allows climbers to train efficiently without unnecessary holds or distractions.

Large Edge Radius for Accurate Strength Testing

Unlike traditional hangboards with sharp edges, the Triple Rung features a large edge radius (50% of the edge depth). This reduces the ability to “catch” skin on the edge and artificially increase friction.

The result is more reliable testing results, as the load is placed on the finger flexor muscles rather than being assisted by skin friction. This makes the board particularly suitable for repeatable strength measurements and structured training programs.

Wide Board for Comfortable Shoulder Positioning

At 55 cm wide, the Triple Rung is wider than most hangboards.
The continuous extruded edge allows climbers to position their hands anywhere along the board, creating a natural shoulder width and reducing strain on the wrists and shoulders during hangs.

Skin-Friendly Wooden Construction

Handmade in the UK from high-quality wood, the Triple Rung is gentler on skin than plastic or resin boards. This allows climbers to train longer and maintain skin condition for climbing sessions and outdoor projects.

Compatible with Lattice Finger Strength Testing

Use the 20 mm edge with the free “My Fingers” assessment to compare your finger strength against the extensive Lattice climber performance database. This makes the Triple Rung a powerful tool for both testing and progressive training.

Minimalist Design for Focused Training

The Triple Rung intentionally excludes pockets. Instead, climbers simply remove fingers from the edge to train two-finger, three-finger, or mono positions, ensuring cleaner loading and less reliance on skin friction.
