VAMRONE 6 Piece Aluminum DIN Rails, 4 Inches Long, 35mm Wide, 7.5mm High, Top Hat Slotted DIN Rail with RoHS, Extra Premium Screws Included for Hardware Components Mounting

They work, are the correct size, and are fairly inexpensive.

Exactly what is needed to mount DIN components like circuit breakers. I returned these because we went with a different style breaker.

This is the first time I have needed this product and I only needed one (or maybe two) short section. Selection of this product gave me what I needed without a lot of excess. Good deal.I am using some Wago products in a small box to extend a circuit. This product allowed me to mount the Wago fixtures much more easily into my box than other options available. The extrusions are well-formed with no voids, no sharp edges, and evenly milled mounting slots. The rails were even supplied with mounting screws! The Wago fixtures fit tightly and will definitely do the job. Thanks for solving my problem.

These items are substantially as described and pictured, except that the screw slots are not all in the same layout. I like to attach these so that loosening the screws without need to remove them completely allow the rails to slide off. This is not possible with some of the slot layouts.

Perfect for what I needed.

These are good quality and size.They can be great if the seller round the edges, which i have done it with grinder but just a suggestion otherwise they are perfect

worked perfectly for my solar breakers

Hold my wifi/bluetooth switch just fine. I would order this again.
