These fit great and clean easily. What I can't just pop off cleans with alcohol
got it for the f2 and did slate embossing with it. it kept my living room clean.
I purchased the Eufymake E1 adapter and it fit perfectly. Nice and snug but not hard to push in. Fit my 4" duct great. Always happy with Samcraft products
All (6) of the different jigs I have purchased from Sam have been easy and quick to set up for both small and very big orders.
