Product Description
CSC1913 — AMSEC CSC1913 Composite Burglary & Fire Safe, UL RSC Level I, 2-hour fire
Most safe listings tell you a rating and hide the tape measure. You find out it does not fit the closet, the cabinet base or the freight elevator after it is on the truck. The CSC1913 measures 24.5"H x 18"W x 19.88"D outside, 19"H x 12-1/2"W x 12.2"D inside, and weighs 318 lbs. It carries UL RSC Level I and 2-hour fire. At 318 lbs this is a freight delivery and a real anchoring job — check the floor and the path in before you order.

Compliance & Codes
Burglary: UL RSC Level I (Residential Security Container). UL tested the safe for 5 minutes of net working time against common hand tools. RSC Level I is a real UL certification, but it is a lower class than TL-15 — if your specification says TL-15, this safe does not meet it.
Fire: 2-hour (120-minute) factory fire rating at 1200°F. AMSEC ran this test itself; it is not a UL certification and AMSEC names no third-party laboratory for it. AMSEC publishes no interior hold temperature for this series. If your specification requires a third-party-verified fire rating, ask us for a UL or ETL model instead.
How to read these ratings. UL-certified means Underwriters Laboratories attacked a sample and it held — TL-15 and RSC are UL classes. ETL/Intertek verified means an independent lab confirmed the manufacturer's fire test. A factory rating means AMSEC ran the test itself. B-Rate is a steel-thickness construction class and is not a certification at all. Purchasing specifications usually name one of these exactly, and a substitution gets a purchase order rejected. If you are buying to a written spec, read us the line and we will tell you whether this safe meets it.

Pro-Installer FAQ
Q: Will the CSC1913 fit where I want to put it?
A: Outside it is 24.5"H x 18"W x 19.88"D, with 19"H x 12-1/2"W x 12.2"D of usable space inside. Measure the doorway and any turn on the route, not just the final spot — on a safe this size the doorway is what stops the delivery. Add clearance in front for the door to swing full open.
Q: Is this the same as a TL-15 safe?
A: No. This safe is UL RSC Level I, which is a genuine UL certification but a lower class than TL-15. TL-15 means 15 minutes of net working time against power tools; UL RSC Level I is a shorter hand-tool test. If a purchasing specification says TL-15, this safe will not pass the submittal — ask us for a TL-15 model instead.
Q: Does the fire rating protect a hard drive or media?
A: Treat it as paper protection. AMSEC publishes no interior hold temperature for this series, and the rating is written around paper documents — paper chars near 400°F. Magnetic media and drives start failing well below that, closer to 125°F. For media you want a dedicated media safe or an internal media chest.
Q: Does it have to be anchored?
A: AMSEC provides 1 anchor hole in the base. At 318 lbs two people with a hand truck can walk this out the door, so anchoring is not optional if the room is ever unattended. Anchor into concrete where you can; on a wood floor, through the joist.
