Good but Heavy
The connectors are very sturdy which is great, but they are heavier than expected. Still good value.

Solid Build Quality
Used these for a tomato greenhouse frame. They hold the pipes securely without slipping. Very happy with the purchase.

Perfect Fit
Fit my 1 inch galvanized pipes perfectly. No wobbling at all. Highly recommend for DIY projects.

Great for Shelving
Built a storage rack in my garage. Holds heavy boxes well. One bolt was slightly tight but manageable.
