or off-line self-locking designs
- EPDM rubber/Neoprene
rubber/Special neoprene
- Maximum service
life
- Superb riding
qualities
- Used between
rail base & tie plates on thru crossings
Eliminates steel tie
plates
& wooden cross ties
- Prevents electrolysis,
corrosion & abrasion

Under all insulated joints
- Absorbs shock
& destructive forces which cause signal failures
- Used on wood
or concrete ties to prolong their service life by ch
anneling
water away from the tie while keeping moisture off at all times
- Produced from
a 65 durometer EPDM elastomer that has outstanding weathering
properties
can be manufactured in any lengths up to 10 foot long
- This rubb
er filler strip is placed
in the rail flange to prevent dirt and debris from filling the
crossing. It absorbs the destructive force from both the rail
deflection and vehicular traffic. It is produced out of a weather
resistant EPDM virgin rubber compound.
- Our FastCamJ Clamps use a patented
cam system for a fast and sturdy hold. Our custom FastCam Tool
allows you to tighten the clamps in seconds.
