The plate dimensions are 2 1/2”. x 3 1/2” . I mounted them with #14 Hex head screws and washers. The casters came without recommendations for mounting. Going into end grain you’ll want to use adequate screw length, 1 1/2” or longer . The mounting holes are fairly close to the edge and going into a 4x4 you’ll need to pre drill to prevent breakout. I have used several sets of these and am very pleased
Approximately 2 1/2 by 3 3/4 inches.
The center bolt of the wheel may be to small check the bolt or the table may be to Havey hope this helps good luck
We have them on some craft work tables with six vises mounted on it. These tables sit in the same spot most of the time and get moved and still glide across the floor.
The plate is 3.74 x 2.64 the bolt holes are spaced 2.87 x 1.77.
Made in China
The holes are roughly 3/8 by 1/2 inch. The distance between the holes are roughly 1 3/4 by 3 inches. I used an 1/2 inch drive lag bolt to mount them
I think 1/4 would work with washers, but the holes were better suited for 5/16". I used 3/8" lag bolts and the lag actually threaded through the opening because it was a bit small.
yes, you can use 1/4" thick bolts, but I believe you can also use 5/16". 3/8" wont fit. BUT you shd check for yourself b/c the manufacturer could always change the size of the holes on the plate.
