I sent an email before ordering because one of my two older Pass-Master units seemed to have a smaller hole than the threads on the spike. Why would there be two different sizes? Anyway, never heard from anyone, so I went ahead and ordered. Then I drilled the holes out slightly and forced the spikes in. Working for now.
Sweethands - Replacement Hardware Kit
The SweetHands stickhandling unit is designed for either dryland use, or screw-in the spikes on the underside for on-ice practice. Each new product contains a kit with spikes.
But what if you misplaced the spikes that came with your original purchase? No worries, Snipers Edge Hockey has the replacement hardware kits to get you back to loving your SweetHands in no time. Each kit comes with instructions, a wrench, and 8 spikes, so it fits either the Pro (8 section) or Rookie (4 section) models.
