## Description

JQDML M8 Screw, 3.94 inch Diameter, DIY End Connectors Suction Cup Adapter for Reciprocating Linear Actuator: desertcart.com: Industrial & Scientific

Review: Great thing in a small package - So I bought this as a stand for my linear actuator and it does the job really well. It's a lot smaller than I thought it would be and when I opened the package and saw how small it was I was afraid that it wasn't going to work for what I needed it for. I must say though I was pleasantly surprised and now see it's small size as a great benefit because it's so much easier to store. I did have to make a base for this but the stand works very well. It doesn't twist or bend and when you hand tighten the bolts at the pivot points it stays locked into place very well. So I would definitely suggest this product just know that it's only about a foot long in total so it is small if that matters for your application.
Review: good unit. works good. - this worked very well. held the 11 inch unit firmly. easily attached to the new machine. it made my day.
