Many models install without drilling or screws and are marketed as tool-free or ready-to-use. A few require simple mounting but are designed to avoid permanent drilling into the frame.
Several descriptions list foam padding, TPR spacers, or proprietary doorframe guards with thick foam pads to help protect the frame and reduce marks.
Assembled dimensions vary by model. In the provided listings, overall lengths range roughly from about 8 inches up to 44 inches, depending on the design.
Most listings show a 300-pound capacity; one listing specifies 330 pounds, so the examples provided span approximately 300–330 lb.
