Mounting hole spacing?
Center to center of screw holes is 1 3/4".
What is the thickness of the top plate? Thanks
Thicker than you would guess, I mic it at 7/32".
I'm not by the dinghy to measure it, but I'd say it's a good 1/8 inch and very robust and solid. Far superior to the chrome plated cast metal ones.
I installed these on a boat that I built recently, I don't have access to them now to measure but I believe thickness was about 1/8".
I don't have one in front of me to measure but, best memory, the top plate is about 1/8" thick. It's not flimsy. The post flares from the underside of the plate. I usually drill the hole for the post and then run a rounding bit in a router to size. Cheers
If you mean the flat brass plate that holds the oarlock sockets, it's the same as the oarlock sockets shown in the Jamestown catalog. If you mean the wood plate that the oarlock is installed in, I believe mine is about 1 3/4" deep and 8" long. Hope this helps,Dave

Great Bronze Top Mount Oralockj Sockets
Read the varying reviews of the Perko top mount oarlocks provided by Jamestown Distributers and was concerned that they may not meet the quality of the Arch Davis Penobscot 14 sailing dinghy that I'm completing. I ordered them on the basis of the quality of material that I've received from Jamestown Distributers (screws, epoxy, etc.). Received them 36 hours after ordering and they were very well finished and definitely up to the standard of quality that I would include in a boat I have invested a substantial amount of time & effort building.

Might be better quality now
I saw the ominous reviews and checked out Perko's web site. The pictures of the item there made the item look to be sand-cast and unburnished as the reviews suggest. I searched the web and found that Shaw & Tenny and Grpaeview also sell top-mount oarlocks. I contacted Grapeview and they said that they sell Perkos and that they are nicely formed & finished, so I ordered a pair. They do look nice. Perhaps Perko has improved quality and Jamestown has older stock?The part number for the item I received from Grapeview is Perko #0831DP0PLB
Catalog text says "burnished" - this is misleading, casting is very rough and needs to be dressed with a file before use. Countersinks are very shallow and need to be deepened to accept #8 or #10 screws. On plus side, inside of socket is well-finished, and it doesn't take long to fix the problems. Overall reasonable value for the price.
Suitable for thier functional use
Yes, they are rough. After all this is a sand casting. It can be honed down & polished if you want the "princess look". You will pay the higher price for labor. My only concern was different size oarlock shafts, which vary from one to the next. I bought two pair and there is a disparity from one to the next. Manufacturer needs better quality control. I will hone out and polish to suit my needs. Overall a very acceptable oarlock for the price.

Not all that bad
I ordered two pairs of these oarlock sockets and found them to be more satisfactory than other reviews had led me to believe. The castings are not "perfect", but appear to be rugged and very appropriate for all but the most elegant rowing skiffs.
Yes, these oarlock sockets are bronze and they do fit a 1/2" shank oarlock. That's really all the praise that can be given. They are poorly cast and, aside from the shaft hole, they are not machined at all. Since they are bronze you can dress them up with a belt sander and end up with an acceptable piece. Better plan on doing some work.
