[SML] Remotely actuated floor locks

[Joe D]

I am still puzzled why I cannot post from my regular e-mail address. Anyway, here it is from a yahoo account.

I am seeking a source for floor locks that can be actuated by either pneumatics or electrically.  I worked for a theater years ago, and we ended up designing our own and building from scratch.  But, I would prefer to avoid that. Are there any systems commercially available?

Thanks for any references,
