For ” Small Conveyor Chains”, numerous back links can be found for coupling and attaching customized units directly on the chains. These links are called attachments. The following standard attachments can be found.
Types and names of typical attachments
normal attachments consist of five sorts for single pitch chains and five kinds for double pitch chains as illustrated beneath. In addition, for single pitch chains, four types of broad attachments, as broad as outer plates, are available. Common attachments for respective chain sizes are listed over the following page.
Tips on how to indicate the specially arranged chains with attachments
A chain with Attachment K1s specially organized as over is indicated as follows:
CJ＋（K1 inner＋PL）×3＋3LL＋PL＋（K1 inner＋PL）×3＋3LL＋K1 outer＋（RL＋K1 outer）×2＋5LL
“CJ” stands to get a C connecting link; “K1 inner”, an inner link Attachment K1; “PL”, an outer link; “3LL”, three hyperlinks from an inner website link to an inner link; “K1 outer”, an outer website link Attachment K1; and “RL”, an 
inner website link, respectively. A “＋” indicator usually means “connection”, and a “×” sign suggests “repeat”. (For one-side attachments this kind of as Attachment A and Attachment SA, the place of attachment plates is on side A in the above illustration.)
Note: When attaching attachments to each and every even-number website link, they’re connected to outer links, except if specified.
