X-Large Outdoor Mezuzah Case – 20cm

This X-Large waterproof mezuzah case is precisely designed to accommodate a 20cm kosher mezuzah scroll (klaf), which is a popular larger size for better readability and halachic preference in many communities. It provides ample internal space (approximately 20.5–21cm usable height) so the scroll slides in easily without forcing or damaging the parchment. Always choose a high-quality, mehudar sofer-written scroll to pair with it.

Yes, this large see-through acrylic mezuzah case is fully waterproof and built specifically for outdoor exposure. The solid construction with bottom-loading design helps prevent rain ingress, while the high-quality acrylic resists UV rays, cracking, and weathering — making it ideal for doorposts, gates, or any external location. For best protection in very harsh climates, mount it away from direct sprinkler spray.

This premium acrylic case offers good UV resistance and clarity, allowing the mezuzah text to remain visible while providing decent protection from sun exposure. However, in extremely hot or intense direct sunlight for long periods, we recommend periodic checking of the scroll. For maximum halachic caution in very sunny areas, consider an opaque or white case to further reflect heat.

Installation is simple and secure: Insert your kosher 20cm mezuzah scroll carefully from the bottom opening, then use the included strong self-adhesive double-sided tape to affix the case to the right side of the doorpost (about one-third from the top, angled according to Ashkenaz or Sephard custom). Ensure the surface is clean and dry for maximum hold. No drilling is required, though optional screws can be added for extra security in windy areas.

Yes, the case itself is halachically permissible and widely used for kosher mezuzah protection. It meets standard requirements for outdoor mezuzot by being waterproof, durable, and allowing easy scroll insertion/removal without damage. Pair it with a certified kosher, mehudar mezuzah scroll written by a qualified sofer stam for full halachic compliance — we offer reliable options to match.

The extra-large 20cm size accommodates longer, higher-quality mezuzah scrolls that often feature larger, clearer lettering — preferred for better mitzvah observance and readability. Its robust waterproof acrylic build and included adhesive make it a premium, long-lasting choice for outdoor entrances compared to standard smaller cases, combining practicality with enhanced protection for your sacred mezuzah.
