Cargo Trailer Vertical Sliding Window 12in x 22in - DOT Approved

In this review the focus is on a practical replacement or add-on window for cargo trailers and small RVs: a 12in x 22in vertical sliding window designed for thin walls. The bottom line is that this window is aimed at DIYers who need a simple, durable ventilation solution; the single biggest reason to buy is the combination of DOT approved tinted tempered glass and a weather-resistant anodized aluminum frame that makes it a solid, safe upgrade for older trailers or new conversions. It is reviewed here from the perspective of fit, installation and daily use.

Key Features

• DOT approved tempered glass: The tinted, tempered glass offers improved safety and privacy while meeting regulatory standards for trailer windows.
• Weather resistant frame: The anodized aluminum frame is lightweight and resists corrosion, which helps the window last in outdoor and marine environments.
• Trim ring with ribbed gaskets: The included trim ring and rubber gaskets simplify sealing and reduce drafts and water intrusion around the cutout.
• Included screen and latch: A durable mesh screen and functioning latch provide insect protection and secure closure when parked or in transit.
• Installation template and pre-drilled holes: The supplied template and pre-drilled mounting holes make rough cutting and fastening faster for DIY installers.
• Fits thin walls: Designed for wall thicknesses of 15/16in to 1-3/8in, this window is suitable for many cargo trailer and camper conversions.

Who It's For

This window is best for DIY trailer owners and RV hobbyists who are converting enclosed cargo trailers, utility trailers, vans or small campers and need improved ventilation and a simple light source. It is appropriate for owners replacing a cracked or scratched window in an older RV who want a safer, tempered glass option.

Those who should look elsewhere include owners with very thick walls over 1-1/2ft or commercial bodies that need custom glass sizes, and buyers who require full-frame insulation or complex integrated blinds and screens not present on this model.

Cons
