There are several on eBay. Do a search for fire extinguisher gauge. Also you may want some tamper seals. It's nice to be able to put on the pull pin after a refill
I'm a big fan of water extinguishers. You can find then on eBay as well. I've bought them from Zoro on eBay and been very happy with them. if you should find some listed by pjfireco he gave me excellent customer service when an order of 3 got lost in the mail. They are also on Craig's List and Facebook Marketplace |
