The ones I bought are rated for 9lbs- perfect
for the wood moulding I wanted for framing out my wallcovering. It was quick, easy, and non-messy. For this project I first measured out how big I wanted my panels- then figured how much trim I would need and how long they should be. I bought MDF moulding already primed (the cheapest kind I could find!) The super friendly guys at our local hardware store cut them to size for me- angle cuts and all. Yay!!
