Fazioli have a range of block heights, from which they chose particular heights for fine tuning the down bearing settings when the piano is strung.

It just seemed like an apt name. We haven't been installing skid plates under our rear duplex sections. Although this makes the process of moving the blocks more difficult, I've been wary of the likelihood of sympathetic vibration between the skid plate and iron plate<font color="#0000FF"> (assuming less than perfect seating)</font>.</div> <div><br></div> <blockquote type="cite" cite>Tuning the halfround oliquots on the skid plates, using my slider is a heck</blockquote> <blockquote type="cite" cite>of alot of fun.

It is made from high density nylon or an equivalent.
