Description

DuraDrive 1/4 in x 2-1/2 in Carbon Steel Mushroom Head Hammer Strike Nail Anchor is good for general purpose anchoring in concrete, block, brick or stone. It can be used light-duty, tamperproof applications. The anchor has a pre-expanded bend at the bottom of the anchor which straightens out to conform to the walls of the hole when hammered into the proper size pre-drilled hole. The anchor will always try to regain its pre-expanded bend which causes constant expansion pressure within the hole. This eliminates the need for any additional tightening or secondary setting operation. The anchor is not recommended for overhead, life-safety or sustained tensile loading applications.

She loves it!
Size: 4 Pieces, Size: 4 Pieces
Tried it as soon as we received it. My dog is a doberman german shepherd mix. I used multiple levels to see what my dog can figure out. It kept her pretty occupied for about 15 minutes and then I readjusted the last level so she could figure it out. With that being said, it can definitely keep them busy for longer! This is going to be a great toy, we love it already. Very durable for my girl, she's a pretty heavy chewer. Very easy to clean because it's a rubber material. The overall puzzle design is also great, really gets them to think. Very easy to stuff treats or kibble inside. Lastly, I LOVE that it's blue and yellow! I wish more toys were in blue and yellow because dogs are color blind! I would definitely consider getting more pieces in the future.

Durable and fun
Size: 4 Pieces, Size: 4 Pieces
I have a chewer who gets bored in the afternoon. She loves these Lego blocks. They’re sturdy enough for a big chewer and they hold her interest . She really enjoys figuring out how to get her breakfast!

Love the idea!
Size: 6 Pieces, Size: 6 Pieces
Love the idea of this product! Arrived 3/25/2026 and started using it the same day. Lab puppies (8 months old) loved it too, until one of the tabs was chewed off 😞 One of the puppies ate something (not this product) last week and was sick & finally threw up the rubber pieces he ate. So they can’t use the toys they love!

Get 8 pack for bigger / stronger dogs
Size: 6 Pieces, Size: 6 Pieces
This is the best puzzle toy i have found for my GSD mix. All around high quality product 10/10. Thick, durable rubbery material that holds up against a strong chewer. Individual pieces are big and bulky enough that i don’t have to worry about my bigger dog accidentally (or intentionally) swallowing a piece, so i don’t need to supervise. That being said, if you have a bigger dog or a strong chewer, i HIGHLY recommend getting the 8 pack if you actually want to keep them busy for more than 20 mins consistently. Bigger dogs just have more leverage to tug on the pieces because obviously…they are bigger, so its just easier for them. The more pieces you add and more tangled/thicker you can make it, the less leverage they have and the harder it is for them to get a good grip. I have a german shepherd/pitbull mix (big boi, v smart, v strong) and i initially got the 4 pack which, after the first few times, only took him about 5 mins to get all the pieces apart even with level 5 connections. So I ordered an additional 6 pieces (i have a total of 10 pieces now) so i could make it harder for him and it was totally worth it. Now I use 8 pieces with level 5 connections and vital essentials freeze dried beef liver treats inside for my GSD and it consistently takes him 30+ mins to get the whole thing apart. I have timed this lol. I can rebuild the 8 pieces multiple different ways to make it more or less challenging (but i always opt for as difficult as possible to keep him entertained for as long as possible) I use the other two pieces with a level 1 or 2 connection for my other dog- bordercollie mix who is not a very strong chewer, he mostly just rolls it around/ licks it until it finally opens or i help him. Both of my dogs are obsessed with this. And i love watching them try to figure it out.
