Scratchers: The scratchers are a tapered coil body design and are able to be used in reverse.  The scratchers are CNC formed from spring steel wire and finished with a black electrocoated finish for maximum corrosion resistance.  Made in the USA.  
 
Replaceable tips are standard.
 
Mounting: The scratchers attach to the sled without drilling, using the supplied mounting brackets.  
 
Storage: The scratchers can be stowed on the supplied bolt-on storage brackets, making for a completely no-drill installation.
