SECURE Your Space
The angled rubber base locks into the floor. 400 lbs of iron stands between you and the door.
One Bar. Two Ways to Stay Safe.
Our 2-in-1 design features interchangeable caps that transform one bar into two solutions. For standard doors, the bar braces under the doorknob. For sliding doors, it wedges securely in the track. Switch between modes in seconds — no tools required. It's the only security bar you'll ever need.
400 Pounds of Don't-Even-Try
This isn't a flimsy aluminum bar that rattles. We engineered this bar from heavy-duty iron rated to withstand 400 lbs of force. The three telescoping sections lock together for a rigid, wobble-free hold that stands between you and unwanted intruders. Once adjusted to the right height, it stays locked in place.
Works on Carpet, Tile, Hardwood — Every Floor
The angled rubber base is specifically engineered to create maximum surface contact on every floor type. Unlike flat-bottom security bars that slide on smooth surfaces like tile and laminate, our angled base grips and holds firm. Whether your doors open onto carpet, hardwood, tile, or laminate, this bar won't slip.
Take It Anywhere You Sleep
Our compact 3-piece design breaks down in seconds. Toss the bar and caps into any suitcase or carry-on bag. It's perfect for hotel rooms where security is a concern, college dorms, vacation rentals, or moving between rooms in your own home. You get the security of a permanently installed lock without the commitment.
Apartment Renters
Can't install deadbolts? This bar reinforces any door without modifications. Perfect for renters who need security without landlord approval.
Solo Travelers

Yes. The angled rubber base is specifically designed to create maximum surface contact on smooth floors like tile, laminate, and hardwood. For the best grip, make sure your floor is clean and dry before placing the bar. On very smooth tile, pressing the base firmly into position creates the strongest hold.
The bar adjusts from 18.25" to 47.50" for standard doors, and 18.25" to 46.50" when using the sliding door caps. This covers virtually all standard residential and commercial doors.
Simply unscrew the current cap and screw on the alternate cap. The standard door caps grip under doorknobs and lever handles. The sliding door caps sit flat in sliding door or window tracks. Switching takes about 10 seconds.
This bar is constructed from heavy-duty iron — not aluminum. The three telescoping sections lock securely together and the bar is rated to withstand 400 lbs of force. Once properly adjusted to the right height, there should be zero wobble.
Absolutely. The bar breaks down into 3 compact pieces that fit easily in a suitcase or carry-on. It's one of the most popular travel security devices on Amazon with over 24,000 reviews. It's also TSA-friendly.
The standard door caps work on any door with a round knob or lever handle, including French doors. For double doors without a center post, you may need two bars (one for each door).
No. The rubber caps on both ends are designed to protect your floors and door hardware. The angled rubber base won't leave marks on any floor type.
Most security bars only work on standard doors with doorknobs. This is the only bar that includes interchangeable caps for both standard doors AND sliding patio doors, giving you 2-in-1 protection from a single product.
The bar comes in Black, White, and Chrome to match your home decor.
You have 30 days to try it risk-free. If you're not completely satisfied, return it for a full refund — no questions asked.
