For ” Smaller Conveyor Chains”, various links are available for coupling and attaching custom units right on the chains. These hyperlinks are called attachments. The following normal attachments can be found.
Types and names of normal attachments
regular attachments involve five types for single pitch chains and 5 kinds for double pitch chains as illustrated beneath. 
Additionally, for single pitch chains, four sorts of wide attachments, as broad as outer plates, can be found. Normal attachments for respective chain sizes are listed over the following page.
How to indicate the specially arranged chains with attachments
A chain with Attachment K1s specially arranged 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 for a C connecting hyperlink; “K1 inner”, an inner hyperlink Attachment K1; “PL”, an outer hyperlink; “3LL”, 3 links from an inner link to an inner hyperlink; “K1 outer”, an outer hyperlink Attachment K1; and “RL”, an inner hyperlink, respectively. A “＋” sign means “connection”, plus a “×” signal indicates “repeat”. (For one-side attachments such as Attachment A and Attachment SA, the place of attachment plates is on side A during the over illustration.)
Note: When attaching attachments to each even-number link, they’re attached to outer hyperlinks, except if specified.
