Yea, I have both standard and heavy duty Cam-Loc boxes for standard BTC's and standard duty Cam-Loc's for my 466C's. I absolutely love them! I hunt in areas of pretty heavy human traffic and have only had one taken (My fault--set on a dead, rotting tree!) The heavy duty cam-loc box seems like overkill to me, but is built like a tank! They are easier to spot in the woods than the standard box. All my cams are bolted to trees with case hardened lag bolts, with hardened washers. Python cables on trees stick out big time in the woods. And if its used to secure the cam to the tree the cam has to be re-aimed each time. Once the box is bolted it keeps the same position. (It takes only a minute to move a cam with screwgun and 2 minutes with a ratchet) Lag bolts basically come in 3 grades. NEVER use standard lags! They WILL snap off. One step up is stainless steel lags. They are sold in the bins at HD and Lowe's. 5/16" X 2 1/2" work well but thick barked trees may do better with 3". By far the BEST way to go is the hardened lags made for API tree steps, backed by hardened 5/16 washers. There is a guy on E-Bay named Montana Freak that sells them. You may have to slightly drill out the mounting holes in the back of the box, so trial fit them at home. I also buy a 4 pack of hardened locks, then spray them and key heads with stone look spraypaint. They are baked in the oven at its lowest temp for several hours, then set in the sun for a week or so. The next set of locks and keys get a different shade so they match. Hope this helped!
