Includes Four locking swivel and locking wheel casters, all mounting hardware for M55 and a jig to mark holes for the mounting brackets.
 
Thank you for your patience and support of PIPERvibe projects! 
 
NOTE: The Jig is on loan to you to make installation simple. When you are finished with it, please return it to me and I will pass it on to the next vibraphonist to use for thier installation. I currently only have 9 jigs. Thank you.
