Line spool and cover
May 10, 2021

When the spool cover broke, I thought I'd have to get a new trimmer since it's hard to find Sears parts. Typed in model number and took me to you. Easy to find parts and easy to order.

I wore out the spool cap on my string trimmer, and parts eventually flew off the trimmer. I was able to order replacement parts easily, quickly and simply by using the Craftsman site and filling out the order. Parts were OEM quality, spool cap may have been actually an upgrade over original part. Arrived within stated time frame, fit exactly, replacement took 3 minutes, then back to work.

I was told the replacement spools for the 151-30383 trimmer were not available. I chanced it and ordered these and they work perfectly.
