“It was great to finally find somewhere to purchase a slide block that would fit Roll Line plates. (I have the 150 Dance plate.) Overall, I'm really happy with these blocks. They were easy to install, feel really secure on the coping, and slide really well.
Just a note for the Roll Line plates and compatibility
It seems the 150 Dance plate is in between Discoblox sizes 2 and 3. I have the size 2. When I position the block as far forward as it will go (as close as possible to the front kingpin), there's quite a big gap between the back of the block and the rear kingpin, which I find easily catches on the coping (you can't really see this in the attached photo, as I had originally positioned them in the centre). I don't get 'stuck', but when it happens, it's an unexpected feeling and doesn't come off the coping as easily as if I landed on the blocks. I measured my skates for the size 3 Discoblox, and that size block would only just not fit between the kingpins. It'd be great to have an in-between size, but this problem is probably because the blocks themselves weren't designed specifically to fit Roll Line plates.”
