This works great on my mower deck where there isn’t a lot of clearance for regular grease connectors.

LockNlube has done it again - produced a great product. I have 3 of their excellent locking heads and love them for most uses. The only drawback is that the diameter of the tips is wider than normal zerk greasing tips, not allowing it to fit into some tight spaces and forcing you to resort to a conventional greasing tip.This new right angle greasing tip is just as narrow as a conventional one It can slip on a zerk fitting easily, lock - grease - unlock and slide off with little effort. All it takes is a small barrel rotation to lock and unlock. It attaches to your grease gun via a zerk fitting on the end eliminating the need to permanently screw anything on your gun. This also provides some extra flexibility. What a fantastic invention! Now, I wish LockNLube would come out with a straight version of this little gem.

The front end grease zerks on my GMC truck are tough to reach with a traditional straight grease hose. This worked well. Good value for the money.

Does the job, but good god is it a fight to get it on and off a zerk.

Works great on those hard to get places on the front end components. Would recommend.

My motorhome is built on a 2018 Ford F53 chassis and the steering box has a recessed zerk fitting. The fitting is pressed into the steering box and cannot be easily removed and replaced with a longer fitting, so I thought I'd give the LockNLube simple 90 a try. I reached out to the LockNLube folks before buying because I wanted to know the diameter of the fitting. I received an email within one day and they answered my questions. Two other Amazon members also answered the same question I posted on the Amazon website. The simple 90 can be used with a conventional grease gun fitting but I thought it would be easier if I ordered their grease coupler as well. Sure enough, both of them work great.

i am using it on my Outlander ATV where the grease points are difficult to access. it helps if you use it with the LockNLube Grease Gun Coupler.

Useless, total waste of money, leaks around zerk/grease nipple when applying grease. Poor quality.
