When it ships & how it's delivered · freight to your door

Paragon builds most kilns to order once your order is placed. We email your confirmed ship date and tracking.

  • The freight carrier calls you to book a delivery window.
  • Delivery is curbside with a liftgate. Have a helper or hand truck to move it inside.
  • Check the crate before you sign. Note any damage on the receipt and send us photos.

Enter your ZIP in "See your delivered price" above the Add to cart button to see freight and your delivered total.

Authorized Paragon dealer · full factory warranty

Brand new and shipped direct from Paragon, so it carries Paragon's full factory warranty. If something goes wrong, call us and we handle the claim with the factory for you.

Warranty terms are in the Warranty and support section below.

Returns: request within 15 days, unused

Because kilns are heavy and often built to order, returns are limited, so we'd rather help you pick the right one up front:

  • Ask within 15 days of purchase or 2 days after delivery, whichever comes first. We issue a return authorization (RA).
  • It must be new, unused (beyond the factory test fire) and in its original packaging.
  • A restocking fee of at least 25% applies, up to 50% on custom, 3-phase or made-to-order units. Return freight is on the buyer unless we made an error.
  • Damaged in transit? Note it on the delivery receipt, send us photos and we'll help with the freight claim.

Read the full return policy

Will it work in my space? Power check

Most 240V kilns need their own circuit and the matching outlet, installed by an electrician. Homes are usually 240V; schools and commercial buildings are often 208V, so pick the voltage that matches your panel.

Send us a photo of your breaker panel or outlet and we'll confirm before your kiln is built: 470-264-3563 (call or text).

Overview

Paragon · Heat Treating Oven · Double Barrel Knifemaking Paragon Double Barrel Knife Oven - KM45 KM45 Double Barrel · 240V · Drop Door with Safety Switch Created for professional bladesmiths and heat-treating specialists, the KM45 Double Barrel offers a spacious, reliable chamber for long blades, high-temperature workloads, and demanding thermal cycles. It runs on 240V single-phase power with Paragon's SENTINEL controller and a drop-down door with a safety interlock switch.
Maximum temperatureUp to 2350°F

What’s included
The oven, assembled and wiredParagon builds and wires it at the factory. The door style you chose is already fitted: a spring-assisted drop door or a side-swing door, both standard at the same price.
Digital controller, factory-installedParagon fits and wires the controller before the kiln leaves the factory. Paragon has been renaming and replacing its controller line and dealer listings are out of date at different dates, so we do not print a model name here. We confirm the exact controller with Paragon when you order.
Type-K thermocouple, installedFitted at the factory and wired to the controller. Type-K is standard across the current Paragon range.
Door safety switchWired in at the factory. It cuts power to the elements the moment you open the door, so you are not reaching into a live chamber.
Cord and plugParagon ships this kiln with a cord and plug. The receptacle type changes with the voltage option you order, so we confirm the exact plug — or whether your configuration is wired direct instead — with Paragon before the order goes in.
Printed manualsA printed instruction manual for the kiln and a separate guide for the controller. Warranty registration is done online at Paragon, and we do not promise a printed warranty card in the crate because we could not confirm one is packed.
Paragon limited warranty — one yearOne year from purchase on this model, per Paragon's published warranty schedule. Paragon does not warrant the Type-K thermocouple, so treat that as a wear part. Keep your proof of purchase.
Not includedNo shelves, posts or kiln furniture ship with a knife oven. The Knifemaker's Heat Treating Kit — four knife holders, eight firebrick supports, a heat treating fork and hot gloves — is a separate purchase, and so are the upgraded touchscreen controller and the gas-inlet option.

Common questions
What makes the KM45 Double Barrel different from the standard KM45?
The Double Barrel version is wider and taller inside, aimed at professional bladesmiths who need extra room for long blades and demanding, repeated thermal cycles.
What does the safety switch do?
The drop-down door is interlocked with a safety switch that cuts power when the door is open, reducing the risk of accidental contact with heating elements during loading and unloading.
Can I add gas atmosphere control?
Yes — a Gas Inlet & Flow Meter is available, with an optional solenoid valve for automated control, to reduce oxidation scale during heat treating.
How does the KM45 Double Barrel compare to the KM45 Pro Double Barrel?
The standard KM45 Double Barrel is a single-zone oven. The KM45 Pro Double Barrel adds three-zone temperature control and rapid-response thermocouples for more precise heat treating of full-length blades.
Is the warranty valid if I buy from Peach State Pottery?
Yes. Peach State Pottery is an authorized Paragon dealer, so your KM45 Double Barrel comes with Paragon's full one-year manufacturer's warranty. Register your oven within 30 days of delivery to activate coverage.
