Installation Notes:
- For vehicles originally equipped with 3/8″ crossmember bolts, open existing holes on the frame to 1/2″. If you prefer to retain 3/8″ fasteners, upgrade the installation hardware to Grade 8 bolts and hardened flat washers.
- Some minor contact between the floorplan and the crossmember may occur due to body bushing settling and deterioration, or a bowed floor pan. Usually, this is not a problem. A hydraulic floor jack with a wood cushion will correct a bowed floor.

Satisfied my need.
Color: Black, Size: 1.37" without hook
Easy to install and my laptop fits solidly. I have a work laptop, tower and my personal laptop. I hated how busy my home office desk looked. Moved my personal laptop underneath and made a big difference.

Perfect for under table/desk mounting
Color: Black, Size: 1.37" without hook
Just what I neeed! These work flawlessly to hide your laptop from taking up desk top space. These do just that! They come with the screws needed to mount them, and the little sticky pade to prevent scratches on your laptop. Perfect Product! A+++

Good mounts but needs a quality improvement with the padding adhesive
Color: White, Size: 1.37" without hook, Color: White, Size: 1.37" without hook
Needs stronger padding. Falling off the next day. Press on, but comes off again. I should not have to apply my own glue, but it's likely what will be needed.

Desk Space Saver—Highly Recommend
Color: White, Size: 1.37" without hook
This under-desk laptop mount is exactly what I needed to declutter my workspace. I used to leave my laptop on the desk or shuffle it around, but now it’s neatly tucked away and easily accessible. Installation was simple—just a few screws and it was ready to go. The mount holds my 14" laptop securely, and the padding inside prevents scratches. I love that I can slide it in and out without hassle, and it frees up valuable desk space for my monitor and documents. If you're looking to streamline your setup, this is a smart and affordable upgrade.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome.
The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings.
One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐
These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️
