MK2 Rail Pads
Customized according to your requirements.
pads have been specially designed for the discontinuous soft mounting of rail
on concrete using chairs and rail fixing clips.
eliminate the load concentrations at the edge of the chairplate :
their chamfered edges reduce the stress concentrations;
pressures under the chair are reduced;
the concrete is protected from cracking.
reduce rail and chair wear :
absorb uneven surfaces;
improve contact between rail and chair.
are manufactured in thermoplastic elastomer and feature lugs to prevent
are specially resistant to wear, shear, crushing, oils, greases, ozone and
oxygen, as well as ultra-violet rays.
Composition : EVA copolymer.

Elongation : 250 % minimum (DIN 53455).
Working stress in compression : - up to 50°C : 20 N/mm2.
up to 70°C : 15 N/mm2.
Service temperature : from -25°C up to +75°C.
other temperatures, please consult us.
Designation and Dimensions:
: dimension of the chair in the rail axis. Standard lengths are : 110, 160 or
: reduced width, always 5 to 8 mm less than the rail foot width (F).
: for mounting a GX42 rail (foot width : F = 131.8 mm) on 160 mm-long chairs :
- 160B x 125.
Application for small size rails:
small size rails, when fastened with clips type 21/020 or 51/015, MK2.0-type
pad - thickness 4 mm, instead of 7 mm - must be used.
