My problem, trying to save taxpayers $ by discouraging thieves.

I know what I would do, but working for a State, I have to work with what
they give me.

Our guardrails have reflectors. The State is implementing new reflectors
going up on their routes. The workers are putting up reflectors mounted on
the blocks or posts for the guardrail. Problem is, the reflectors are
mounted on aluminum! Ok, someone at the top should've seen this one coming,
especially with the economy being the way it is.

The reflectors are installed using 2, 3/8" x 2" lags with a 7/16" head. The
thieves will not bother the reflectors on narrow shoulders, or on dangerous
curves. But, where a full width shoulder exists, the reflectors disappear..
Besides being pretty, the aluminum is probably what is making them
disappear.

Changing material from aluminum is out of the question. Remember, this is a
State Agency, and come hell or high water, some nitwit at the top wants
this to work.

My initial thought is to have the workers dab PL on the heads of the lags
after installing. But, a set of vice grips would still back out the lags.

Aside from having the State Troopers sit and wait, any ideas? Besides, they
have better things to do, like responding to accidents from people hitting
unmarked guardrails!

Thanks

If they are secured to a flat surface, glue them on and additional
security screws or snap rivets. You can get bolts with heads that can
be snapped off leaving a hemispherical head that can't be gripped.
The corresponding nuts are similar.
The problem with all these things except the glue is the existance of
battery powered angle grinders.
You're lucky that's all they steal. Here in the UK is copper cable.
Regardless of the voltage.
