Each clamp is adjustable to hold screens up to 23” wide, fully compatible with roller frames. These clamps are equipped with a rear cross bar that acts as a Linear Glide for side-to-side, left-to-right adjustment, bolstering flexibility.

The 12” long side clamp body enables more capacity for adjustment from front to back when registering, or when needing to gang up prints on a screen, which is always awesome.

Riley Hopkins Reviews



I've been screen printing for 5 years, curing everything with a flash... time for the big upgrade. I'm impressed with the overall quality [of the RileyCure 245]. It took a few hours to get this set up, and I was running test prints the day it arrived. At this point, the unit can cure shirts just about as fast as I can print so I am very happy. My settings can probably be tweaked a little better, but this machine is really saving me a lot of time and ensuring consistency of cure. So far, this has basically doubled my productivity and then some.

We don’t have enough words to express how happy we are with our decision to upgrade to our Riley 300. Everything about the press is amazing! Hands down it has the looks but it also has an amazing set of features. Our favorite thing about the Riley 300 is that it is completely toolless which makes all those fine adjustments so easy. Oh, and the off-contact adjustment, straight-up perfection! You guys nailed it with this one!

Such a great tool! Really takes the guesswork out of placement as you're going through different size garments. Very well made and heavy duty! install took only 10 min or less! laser is very well made and super bright, and the charger that came with the unit is great! seriously just buy it and pull the trigger!

Put this [RileyFlash 1818] together this weekend and right off the bat I was impressed with the quality. The stand is good heavy metal and very solid. I bought some other dryers on Amazon cause it was cheaper and they were not close to this one. Thin metal and they literally burned out on me (caught fire). I wish I had spent the money on this one the first time.
