The adjustable ‘Hard Clip’ has been designed specifically to hold the rail down into position so that rail lift will not occur.
The hard clip must not be used when a resilient pad is introduced under rail or where the track running machine is constantly travelling at high speed, irrespective of wheel loads.
HoldFast clips are manufactured from ductile iron. Whilst the structure of ductile iron is similar to that of carbon steel, containing randomly dispersed spherical particles of graphite, it has the advantage of better castability than steel, giving a smooth clean profile and more strength for less expense.
Options are available for Galvanising and cadmium plating, in addition to other coatings to suit customer requirements if they are required.

The adjustable soft clip has been designed specifically to allow the rail to lift a pre-determined amount to cater for rail wave.
Allowing the rail to lift in this way reduces stresses and strains in the rail and clips, and fatigue stresses in the holding down bolt/studs.
The Soft Clip is the ideal product when rails are welded in a thermic process, making long runs, or when rail is supported by a resilient pad.

About Us
The HoldFast philosophy is to work closely with civil engineering consultants and civil contractors to achieve the most cost effective solution to a rail track problem. We combine long term expertise with leading technical and environmental solutions to bring a stress-free rail track system.
Design & Installation
HoldFast advise, with the customers requirements in mind, on the best design and installation procedures such as long life and minimum demands on maintenance. The HoldFast track technology is determined by progressive thinking based on the latest technical advances.
Superior Quality
HoldFast clips are produced by the well established ‘Shell Moulded Process’ which enables all castings to be very accurately produced and consistent to the drawings, to comply with B.S.E.N. GJS 1563 and DIN 1693. The clips are designed so that they can be tailor made for any rail section.
The clips accommodate rail expansion and contraction due to climate conditions, even though the rail is held in positive lateral alignment.
Clips are fitted in pairs, opposite each other, with calculations determining both diameter and longitudinal centres of fixing bolts.
