Hollon WS-BIO-1 Biometric Wall Safe
The Hollon WS-BIO-1 is an in-wall safe that opens with a fingerprint. The biometric reader stores up to 20 fingerprints, so everyone who needs access can be enrolled, and a key override is included for times the reader cannot be used. It is meant for quick access to the things you reach for often: a handgun for home defense, cash, jewelry, passports and spare keys.
The safe installs in the wall between studs. Dealer listings give an in-wall base of 21" x 13 7/8" x 3 3/4" behind a front flange of about 22" x 15" (one dealer lists the front as 22" x 16"), with an overall depth of 4". The interior measures 19" high, 14" wide and 3 1/8" deep, about 0.48 cubic feet, with two interior shelves. The body is heavy-gauge steel and the door is held by two round locking bolts.
Installing it follows the usual in-wall steps. Locate the studs, confirm the bay is clear of wiring, pipes and ductwork, mark the opening to the base size, cut the drywall, test-fit the safe and fasten the body to the framing on both sides. Enroll fingerprints before you hang anything over it, and test the override key once so you know it works.
Mount it at eye or arm level where it is easy to reach, then cover it with a picture, a mirror or clothing in a closet. A wall safe relies on concealment and on a solid connection to the framing. It has no fire rating.

Frequently Asked Questions
How many fingerprints can the WS-BIO-1 store?
Up to 20. That leaves room to enroll more than one finger for each person, which helps if one finger is cut or bandaged.
Can I open it without a fingerprint?
Yes. A key override is included. Keep the key somewhere secure outside the safe, since it is your way in if the reader or battery fails.
How deep does my wall need to be?
The overall depth is 4" and the in-wall base is 3 3/4" deep. A 2x4 wall gives 3 1/2" of stud depth plus the thickness of the drywall, so in a typical interior wall the base fits. Check the cavity for wiring, pipes and ductwork before you cut.
Does it fit walls framed 16 or 24 inches on center?
At 16" on center there is about 14 1/2" between studs, and the 13 7/8" wide base fits between them. At 24" on center the opening is wider than the safe, so add a piece of vertical blocking next to it to have framing to fasten to on both sides.
The fingerprint reader is not recognizing me. What should I try?
Wipe the sensor and make sure your finger is clean and dry, then place it flat in the same position you used when you enrolled. If the reader is slow or unresponsive overall, replace the battery first; low power is the most common cause. Use the override key if needed, and re-enroll the finger if the problem continues.
Where is the best place to mount it?
Hollon's dealers suggest eye or arm level, where the door is easy to reach and the reader is easy to use. Common spots are inside a closet, behind a hanging picture or mirror, or behind furniture.
Will a handgun fit inside?
The interior is 19" high, 14" wide and 3 1/8" deep. Many compact and full-size handguns fit lying flat, but measure your firearm's thickness at the grip and sights against the 3 1/8" depth before buying.
Is the WS-BIO-1 fire or water resistant?
Hollon does not give it a fire or water rating. It is built for quick, concealed access, not for fire protection.
Is a wall safe as secure as a floor safe?
No, and it is not meant to be. A wall safe's protection comes mostly from being hidden and from how firmly it is fastened into the framing or set in masonry. For high-value items or long-term storage, a heavier floor safe that can be anchored is the better choice.
How is the WS-BIO-1 different from the WSE-2114?
They share the in-wall base size and interior dimensions. The WS-BIO-1 opens with a fingerprint and stores up to 20 prints; the WSE-2114 opens with a keypad that holds a master code and one user code. Both include an override key.
