Hollon TTW-2015 C/E B-Rated Through-The-Wall Depository Safe
The Hollon TTW-2015 C/E accepts deposits through a wall. A 60-degree chute runs from a slot on the other side of the wall down into a B-rated steel safe body, which suits night drops, rental offices, and businesses that take payments after hours.
The safe has a 1/2" solid steel door and five 1-1/4" solid steel active bolts. A drill and ballistic resistant hardplate protects the lock, backed by an internal spring-loaded relocker.
Two lock versions are offered: the TTW-2015C with a UL Listed Group II Sargent & Greenleaf mechanical dial, or the TTW-2015E with a UL Listed Type 1 S&G electronic keypad.

Frequently Asked Questions
What is the difference between the Hollon TTW-2015C and TTW-2015E models?
The safe body and wall chute are the same. The TTW-2015C has a UL Listed Group II S&G mechanical combination dial, and the TTW-2015E has a UL Listed Type 1 S&G electronic keypad.
What are the dimensions of the through-the-wall drop chute?
The chute face is 4-3/4" H x 9-1/2" W with a 3/4" H x 6" W deposit slot. The chute runs at a 60-degree angle, and the safe and chute together stand 40-1/4" tall.
How does the spring-loaded relocker system work?
The lock sits behind a drill and ballistic resistant hardplate. If someone drills or punches the lock, the spring-loaded relocker fires and holds the bolts closed.
What are the internal and external body dimensions?
The safe body is 20" H x 15" W x 15" D outside. The listed interior is 19-3/4" H x 14-3/4" W x 12" D.
Does the Hollon TTW-2015 safe include mounting hardware?
No. The base has four pre-drilled anchor holes for a concrete floor, but anchors are bought separately to suit your floor.
What wall thickness does the chute fit?
The chute is made for a standard 2x4 or 2x6 framed wall. Masonry or thicker walls need to be checked before ordering; email info@garagetoolsstorage.com, or call or text 765-221-3366 with your wall details.
The TTW-2015E keypad will not open. What should I try?
Replace the battery first. Weak or dead batteries are the most common cause, and the S&G keypad keeps its code when the battery is changed. If the lock still does not respond, email info@garagetoolsstorage.com, or call or text 765-221-3366.
What fits through the 3/4 inch by 6 inch slot?
Envelopes, checks, folded cash and rent payments. The slot is too narrow for bank bags or bulky pouches, which suit a front-load or hopper drop safe instead.
Can the interior shelf be removed?
Yes. The safe comes with one removable shelf, so you can separate deposits from logs or remove it for open space.
Who installs a through-the-wall safe?
Installation is up to the buyer. Most owners use a carpenter or contractor to cut the wall opening, set the chute and anchor the safe to the floor. When the safe arrives, inspect the packaging and the safe before you sign for it, and report any damage to us within 24 hours.
