Review on Talboys 916140 Aluminum Lab Frame Diameter by Jonathan Clark

Better than I hoped. Very strong. Use it for aquascaping in my aquarium. Currently holding an 18" piece of branch coral at a 90 degree angle to the side of another piece of branch coral, very strong. Uses a 0.51" diameter piece, uses a 1/2" masonry bit to drill through the stone, and it fits well.Highly recommend them if you are doing anything that requires structural integrity.
