The Complete Guide to Chain

2.3.3 SA Attachment

For the SA attachment, the link plate is extended on one side of the chain, and one or two bolt holes are installed. These are called SA-1 or SA-2 depending on the number of the bolt holes (Figure 2.22). The attachment interval can vary the same as the A attachment. These attachments may be adapted for use with hooks or slats (Figure 2.23).

The SA attachment is simpler and stronger than the A attachment, and may receive bending and twisting force depending on the direction of the loads.

The return side of the chains can be supported by guide rails on the rollers unless bolts extend into the attachment.
