Half Handles: Modular U-Handle Sections for Custom Stroke Lengths

Customize your U-Handle with mix-and-match flexibility.

ProtoBrix Half Handles are interchangeable actuator sections that let you configure your U-Handle to match the exact stroke length and functionality your prototype requires.

Each half handle defines one side of the dual-actuation system.

Available in 80 mm, 100 mm, and 120 mm versions,  allowing you to combine two halves of different lengths for asymmetric or custom movement profiles.

Key Features

• Modular configuration: Combine half handles of different lengths (e.g. 80 mm + 120 mm) to tailor the total actuator travel to your design needs.

• Three stroke options: 80 mm, 100 mm, or 120 mm — standardized dimensions for predictable and repeatable mechanical behavior.

• Full compatibility: Fits seamlessly with any ProtoBrix U-Handle system and Internal Components.

• Quick replacement: Swap one half without disassembling the full handle — ideal for rapid iterations during R&D testing.

• Precision design: Manufactured with tight tolerances to ensure perfect alignment, smooth motion, and reliable test performance.

Why It Matters

Instead of purchasing multiple full handles for different prototype setups, Half Handles let you mix, match, and reconfigure your actuator in seconds.

This modularity gives you fine control over stroke length, reduces cost, and increases flexibility during concept validation and functional testing.
