Anyone know info on this chain?

I found a place that sells #48 single-roll roller chain for cheap. Does anyone know the pitch of this chain?

not off the top of my head, but you could check someplace like rural king or tractor supply, somplace that sells farm equipment, they should keep a few different types of chain around and would probably be able to tell you the pitch of a #48 chain if you talk to the right person.

now there's an idea. It is for a garage door if that helps

Been a rough week so far with kids home sick . I got some chain this past weekend from locojoe and 450redrider (Thanks guys). I spoke with a couple of garage door companies as well. The first gave me a resounding NO with excuses about "insurance and liability" but the second was more than happy to help out. He said he would start pulling chains for me and to call him back Friday . So I should be able to get it all chained up and rolling this week. Almost where I want it. The guy I was talking to said the chains he had were #40 or #41. Will this chain work or do I need #35 like kuttnhack said? What is the difference?

No Problem happy to help, This might help with the chain hunt, as far as I can see the 40 or 41 chain should work it will just be a little bit wider than the cruiser chain
cruiser bicycle chain uses 3/16" wide rollers 1/2" pitch.
multi-speed bicycle chain uses 5/32" wide rollers 1/2" pitch
Chain Number / Pitch / Between Inner Plates
25 / 1/4" / 1/8"
35 / 3/8" / 3/16"
40 / 1/2" / 5/16"
41 / 1/2" / 1/4"
50 / 5/8" / 3/8"

wikipedia told me this... just had to find out what to google

The chain in use on modern bicycles has a 1/2" pitch, which is ANSI standard #40, where the 4 indicates the pitch of the chain in eighths of an inch, and metric #8, where the 8 indicates the pitch in sixteenths of an inch.

so it is going to be 1/2" pitch, just wide, which I can deal with.

Well, kind of, but not quite.

There's more than one ANSI chain that has a 1/2" pitch and ~.312" roller diameter.
ANSI #40 has rollers that are 5/16" wide, which is too wide. It may work, but it will have a lot of sideways play on a bicycle.

Single-speed bicycle chain uses rollers that are about 3/16" wide (external-gear multi-speed bikes use the same pitch and roller diameter, but in even narrower widths).

ANSI #41 chain is narrower than #40; #41 is the same but has rollers only a quarter-inch wide. Still loose, but cuts the error of #40 in half.

---------

McMaster-Carr has the specs of a lot of ANSI and ISO chains on their website, if you look.
There doesn't seem to be an ANSI number for any bicycle chain. And the narrowest ANSI chains seem to be a quarter-inch (roller widths).

By the by--McMaster even carries some double-pitch chain that will fit on single-speed bicycle sprockets.
This is ANSI chain #C2040, it has the same .312" roller diameter and has 5/16" roller widths (so it has a lot of sideways play) but has links one inch long instead of a half-inch.
Looks olde-timey but isn't really, kind of like a poor man's skip tooth chain.

I bought some of this to use on a board-track racer bike I built, it rides the sprockets just fine but the frame did not have enough sideways clearance and the chain would rub the seatstays, so I ended up using normal chain. They sell half-links for it too, but the half-link is still an inch long,,, so be warned, your frame needs some looong horizontal dropouts to take up any remaining slack.
