Several items include all necessary mounting hardware or attachment screws, and many listings state hole centers or other mounting details. However, not every product specifies included hardware—check the individual product page to confirm what’s included.
The stretch‑on covers are designed to fit round knobs roughly 1" to about 1‑1/2" in diameter and can also adapt to square knobs when measured diagonally.
Many items emphasize beginner‑friendly or tool‑free installation, and some include all necessary mounting hardware. Customer reviews generally note that covers and several knobs are easy to install.
Warranty coverage varies by item: some listings show a limited lifetime warranty, one lists a 30‑day limited warranty, and other products don’t clearly specify terms. Always check the individual product page for exact warranty details.
