My first rack was from a nationaly known Tractor company. I was just starting out and was looking for a cheap alternative. They have no locking mechanisim so I came up with my own way to lock up my trimmers. Everything was fine until one day my partner and I stopped for lunch. When we came out everything was gone rack, trimmers,edgers etc. The racks were so cheaply made the crooks just bent the posts back and forth until the bars bent and eventually broke off. Thank goodness for insurance. I have a better version now but from what I can tell from your racks the newer one has a long way to go to reach your quality. Your racks sure would be a blessing.
