Consdering installing a security post at the end of my tar-mack drive.
The type that I can let down.
There are two security posts on the market, those to cement in and
those using 12mm anchor bolts.
I have never used these bolts before ,so I presume you drill a hole
first. Considering thin layers of tar-mack, Are the bolts likely to
hold ? Or should I go for the ones that cement in ,thus making a mess
of the drive?
