[SML] Remotely actuated floor locks

[gbierly]

> 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?

We have built our own through suggestions from here on list and the Fulton Opera House staff from something like these

and then welding a plate to a bolt to make the pad.  We started with double acting cylinders but now have been switching over to the spring return single acting cylinders.  

We do have 8 Spoon Group casters that are pneumatically locking that are really slick but $1000 for a set of 4 I just don't have the budget to add to the inventory.
