OK, I see that 1 and 2 are the set and I meant 3 when I said 2. I can, but I'd rather not make the necessary mods to the gate frame to let in a lock case mech. I'd have to weld in tabs for the mounting screws as well. I'd much prefer just doing the bore for no. 1 with the no. 2 strike.

I looked at the UK source and FOA I didn't see anything near $25 US and with shipping and tariff added, I see a min of $100. It not that important to me to change this over. I guess I can search for the specs on installation.
I was hoping for a more barn like industrial solution as might be found on a commercial rolling door. I have looked on and off for years. Google has been no help. One sided affairs are available.

There is one other problem and I should have shown a pic. The redwood fencing is on the outside of the frame making the condition 2 3/4" with the steel frame off center. I'm not sure I could extend the exterior cylinder out 3/4". The point is I'd hate to get that shipped only to find I can't use it.
