Shock Mitigation Seat Rail System
A BETTER RAIL SYSTEM FOR MOUNTING SHOCK MITIGATION SEATS
This system is specifically designed for the marine environment, giving you a flexible cockpit layout with fast, hassle-free reconfiguration. We tested this system over 20 kN (25 kN for the 27mm rail) to meet HSC regulations.
How Does it Work?
Seats are mounted on four trolleys that run on parallel rails. Two of the trolleys have pinstops that fit into the holes in the rails. Two trolleys are free sliding. To adjust the trolley location, simply raise the two pinstops and slide to a new location.
- Strong – tested to over 20 kN (25 kN for the 27mm rail)
- Adaptable – can be fitted to dive tank racks, weapons racks, deck boxes etc.
- Compact – minimum intrusion on cockpit sole
- Black hardcoat-anodized; maximum corrosion resistance
- High strength 6061-T6 aluminum low-profile rail
- Hardcoat-anodized for maximum protection
- Pinstop holes for maximum flexibility in seat spacing
- Countersunk fasteners for flush fitting
- Underside of rail recess for mastic sealant

Installation and Maintenance
Flush clean with fresh water and mild detergent. To reduce friction further, use McLube® high-performance dry lubricant. Do not use oils or greases. For added protection against corrosion, Harken Industrial recommends using Tef-Gel® corrosion eliminator on the fasteners when installing the rail.
The Shock Mitigation Seat Rail System should only be installed by a competent person or organization in order to meet the requirements of HSC regulations.
All rails listed are designed to use stainless steel fasteners. Attachment to the vessel must be in accordance with HSC regulations. Harken Industrial does not recommend installing with aluminium fasteners. Use of non- stainless-steel fasteners is at the liability of the installer and must be designed to meet the requirements of HSC regulations.
Always use thread locking solution or locknuts. Precise rail alignment at joints is critical for smooth-running cars.
