Finna install a letterbox next weekend, including the concrete base. You're supposed to install the anchor bolts after the concrete has dried by drilling a hole, but can I instead fasten the bolts to the letterbox then place it in the still-drying cement? Then, the next day, I can tighten the bolts to activate the wedge function.
>>3010260You can. That technique is commonly used on street lights.
>>3010260use j bolts not wedges
Wedges a shit
>>3010272fuck tapconslittle tiny bitchass threads rust off and they get loose in 5 years
>>3010264This. If you're setting them in wet concrete just use j bolts or regular bolts with shit welded to the heads...
>>3010260Try and tell us about it, though I assume it won't turn. Just use a normal stainless bolt then, held on with a nut in the box.
>>3010260>pound threaded rod into the ground in the right dimensions>make sure they will stay nice and plumb until the concrete sets>for each rod use bolts to secure a pair of fender washers a couple inches apart inside the eventual concrete pad>pour concrete and wait for it to set>cut down rod to the correct height (file it to avoid sharp edges)>mount letterbox
>>3010317>boltsNuts obviously
