Product Review: Grabbit

Permanent Linkby wisconsin_cur on Mon Dec 06, 2010 5:38 am

So I am putzing around in the farm store looking at tarps and trying to figure out how to get a couple of jobs done when I come across a product I never noticed before:


The basic idea is that one piece "the dogbone" goes on the underside of the the tarp and a second piece slides onto the dogbone from above. Supposedly it can be used to connect two tarps together. I just used it to attach two tarps: one canvas and one plastic to a building or anything else solid.

The instructions were wanting but after squinting for several minutes at the picture on the package and about twenty minutes of failed attempts I figured out which end of the dogbone was to face out:


The big draw back is that the center hole has an air space between the plastic dogbone and the surface it will be connected to. I lost one dogbone to over tightening the screw with my electric drill. You do not have to overtighten very far for the thing to bust in two pieces.

The canvas tarp was hung just inside the entrance to my new woodshed to keep the rain and snow off of the most exposed wood near the entrance. I installed three "Grabbits" on the inside (one was lost to overtightening) and then slid the exterior piece over the tarp (see below for pic). Using the canvas tarp required the use of a rubber mallet to get the "Grabbit" attached but it was tight enough that I feel confident that it will hold for the meantime.

Attaching a plastic tarp, however, I did not feel that the Grabbit was tight enough for a good hold. I doubled the tarp over to gain some additional thinkness and then the exterior piece slid on with just a little persuasion from the heel of my hand.


So far both seem to be holding well under normal usage. At almost $8.00 for a package of 4 I felt they were a little pricy. I will be curious to see how long the plastic lasts and if it extends the life of the tarp itself. No doubt the Grabbits protected under the woodshed will last longer than the exposed ones holding the tarp over the hay bales. I will also be curious to see how they handle the stress of the animals applying pressure on the tarp as they eat the bales underneath. I am hopeful that the Grabbits will outlast the plastic tarp.

I'll provide a longer term view as time progresses but at this point I would reccommend them if you have an application for which they are the perfect fit. I definitly would re-use them for the canvas tarp to protect the wood, an application where I really did not care for my other options and I think they will perform for the medium to long run. The jury is out on if I would re-use them on the plastic tarp covering the hay bales. If they preform well, I will consider replacing the platic tarp with another canvas one and placing hay there in future winters.
