The Vevor RV screen door protector is designed to help keep pets safely inside while allowing airflow through your RV entry door. Its aluminum alloy construction with a baked paint finish provides lightweight, rust-resistant durability for long-term use. The reinforced two-piece frame adds stability against scratches and impact from larger pets. It installs quickly onto an existing RV door frame with a retractable latch and metal guide. This protector also works for patio or entry doors in homes where added pet containment is needed.
