ASD 18 in New Construction Mounting Plate with Asymmetric Round Hole

In this review the ASD 18 in New Construction Mounting Plate with an asymmetric round hole is evaluated for contractors and DIYers who install recessed LED lighting in new builds or remodels. The single biggest reason to consider this mounting plate is its multipurpose design that accommodates 8 in, 10 in, and 12 in recessed LED housings, making it a convenient universal solution for varied ceiling plans. The plate's alignment notches and included mounting holes simplify layout across multiple fixtures, and installation is straightforward for anyone comfortable with basic electrical box positioning.

Key Features

• Multipurpose sizing: The plate supports 8 in, 10 in, and 12 in recessed lights so one product covers multiple fixture sizes on the same job.
• Asymmetric round hole: The unique hole shape helps center and align many round wafer lights while allowing flexibility in orientation.
• Included mounting holes and tracks: Prepunched holes and tracks fit a variety of joist layouts and reduce time spent measuring and marking.
• Alignment notches: Notches along the plate make it easier to align multiple plates in a straight run without repeated measuring.
• Quick installation: The plate can be positioned and secured with screws or nails and also provides a place to fix the J-box during new construction.

Who It's For

This mounting plate is a good fit for electricians, remodelers, and experienced DIYers working on new construction or full ceiling replacements who want a single plate to handle 8 in through 12 in recessed housings. It is especially useful on sites where multiple fixture sizes are used, or when alignment across several lights matters.

It is less suitable for those who only need a 6 in solution or for retrofit installs where the existing ceiling cutouts and framing differ significantly; customers who reported fit issues with 6 in fixtures should consider a plate specifically made for smaller cans.

Pros & Cons

Pros

• Versatile sizing removes the need to stock separate plates for 8 in, 10 in, and 12 in fixtures.
• Alignment notches and tracks speed up layout when installing multiple cans.
• Easy to secure J-box and position the plate with basic tools, saving installation time.
• Durable flat steel construction provides a stable mounting surface in most ceiling spaces.

Cons

• Some users noted the plate can feel flimsy compared with heavier brackets depending on handling.
• Not designed for 6 in fixtures, so it will not fit smaller recessed lights without modification.
