Stafford Metric Shaft Collars are fully metric in all specifications, including the clamping screws.

Available only from Stafford, the Hinge Collar features a triple-link hinge and captive screw in one unit, combining the flexibility of the two-piece collar with the simplicity of the one-piece.

Stafford’s exclusive Hinge Shaft Collars are perfect where fast operation is required, such as hostile environments or situations where there are space and time constraints. Hinge Shaft Collars are functionally similar to two-piece collars, for use on standard round shafts, hard or soft, as well as on thin wall tube or over a split hub.

They are easy to assemble, reposition, and take apart; eliminating fumbling, lost screws and wasted time. Hinge Shaft Collars provide the same axial holding power as conventional collars. They have a smooth bore that will not damage shafts.

  • Steel
  • Stainless Steel

Perfect! Easy, convenient, definitely recommend
Size: 100LBS, Size: 100LBS
I am so glad I found this base that I can just fill with water. After screwing on the wheels, I used my garden hose to fill it with water and put my 1.5 inch diameter umbrella in and tightened it. Easy peasy. I love that it rolls and I can move it wherever I want, and also lock two of the wheels if needed. Definitely would recommend this one!

Size: 100LBS
Happy with my purchase. Sturdy well built, love that it has wheels makes it easy to move around and wheels lock in place. I choose to fill it with sand and water as it gets really windy where we live this will prevent my umbrella flying to the neighbors house again 😅

Must Read before Purchasing!!!! Height is lost if you use this base!!!!
Size: 100LBS
I was so very excited about this for our umbrella - and then I put it together. I called my adult son to come and take a look - I had to be doing something wrong. To our dismay, I was not. The lowest pole in the umbrella system has 4 welded pieces with holes meant to connect to the legs, thus stabilizing the structure. The lowest pole measures (guestimate) 3 feet. When you choose this system, you do not use the original cross-bars, nor the original lowest pole with the 4 welded pieces. Rather, you use a newly provided lowest piece roughly measuring a foot. In doing so, the structure loses a total of almost 2 feet. For average-height individuals, this would not be a problem. For individuals 6' or greater, this is quite a problem. My son is 6'6. My husband is 6'2. I really wanted the portability of the product. However, we will be returning it for the kind that rest on the cross-bars. I wish someone had mentioned this in the reviews I read and saved me the trouble.

Happy hound!
Color: Yellow, Color: Yellow
My 2 yr old bloodhound destroys every toy in minutes, but not this one. My husband and I actually buy toys to see how long they last for fun. Although the croc is NOT indestructible, it lasts a whole lot longer than most. After an hr or so, I took away the only piece he's chewed off which is part of the back leg. Otherwise nothing else is missing off the croc. Our boy has been very occupied with this new toy and we're satisfied with his new distraction!

Definitely a tough toy
Color: Blue
This is one of the few toys my Boxer/american bulldog mix hasn’t been able to tear apart. He loves chewing on it and I love that he doesn’t chew on stuff he shouldn’t. I have such an issue with toys being torn apart the day I bring them home. I wish there was a safe way for it to have a squeaker since he loves squeakers but I don’t think that is possible.
