Two straight brackets for regular modular looms so that you can set the looms end to end. To use this for the 6 peg modular or any set of four modulars you will need two packets. The straight brackets aren't needed for the 6 peg mod unless you choose to put it together as a straight rake loom. You can still knit a flat panel when it is set up in the round by going back and forth and not connecting the knitting.
The brackets are more for when you are using the larger modular pairs to make a bigger loom.
These are not to be used with the 2 way adjustable looms.
