Review on Oxford OF440 Anchor Layered Hardened by Antonio Urbina

Excellent product. The only issue was the need for a 12mm and 16mm hole. I had to buy these off eBay as they are not available from Home Depot/Lowe's in the US which delayed installation. Instructions are few, but there are plenty of online help on YouTube. The install took about 2 hours from start to finish, slow and double checked. The anchors require some convincing to get into place but overall not bad, the 16mm bit is the right size. Once completed, the product is extremely durable with room to thread some large chains to tie multiple items together.
