MSA 506277 Dyna-Glide Fall Arrester Aluminum 400 lb Capacity

The MSA 506277 Dyna-Glide Fall Arrester is an aluminum fall arrest device designed for use with the MSA Dyna-Glide® Rigid Rail Fall Protection System. Built for workers climbing ladders, towers, and a wide range of industrial structures, this fall arrester provides reliable, hands-free protection during both ascent and descent.

The Dyna-Glide system is engineered for versatility — it can be mounted to existing ladders, lattice tower corners, and other structurally sound surfaces. With appropriate MSA mounting assemblies, it can be configured for vertical travel, horizontal travel, or routes that include curves, corners, and obstacles. Multiple workers can use the system simultaneously for added jobsite efficiency.

Key Features:

• 400 lb weight capacity for robust fall protection
• Lightweight aluminum and stainless steel construction for durable, corrosion-resistant performance
• O-Ring connection type for secure attachment to the Dyna-Glide rail system
• Smooth, bind-free travel inside the rail during ascent and descent
• Hands-free operation — allows workers to ascend and descend without manually managing the arrester
• Vertical and horizontal mobility supported for complex climbing routes
• Compatible with complete MSA rescue system components
• Suitable for general industrial, oil & gas, utility, and working-at-heights applications
• Meets all applicable OSHA standards
• Made in the USA

The MSA 506277 is sold individually (1 EA) and is intended for use exclusively as part of the MSA Dyna-Glide® Climbing Protection System. A variety of MSA accessories are available to enhance mobility and provide continuous fall protection across demanding work environments.
