Three 9” high sections stack on top of each other. The stand is separate. The counterbalanced hinge gets attached to the kiln and floor for stability. The kiln is very easy to assemble and disassemble. The kiln sections plug into the separate control panel.  More about sectional construction...
Stainless steel wrapped around shaped firebrick. There are three adjustable clamps welded to each casing. All assembly is with stainless steel screws. Unique shallow side arches create super-strong sides and allow for plenty of space for air circulation around kiln shelves.
Welded angle iron counterbalance system with springs. Safety latch included. Welded angle iron with leveling bolts.
The welded angle-iron stand is separate but attached to the case. It includes leveling bolts and holes for anchoring the kiln to the floor. The angle-iron frame is covered with a layer of aluminized steel which the bottom of the kiln sits on.
A proprietary brick coating is applied to all interior surfaces of the kiln. This is put on before the element holders are inserted. This coating penetrates the firebrick and fuses the surface on a microscopic level which helps prevent dusting and crumbling of the fragile firebrick.
Solid ceramic peephole plugs with full 1” diameter. Three total: one per section.
Limited Three Year Warranty

Durability

Hard Ceramic Element Holders Make L&L Kilns More Durable
Durability, Repairability, Better Heat Transfer. The smooth, hard surface of the inside ceramic channel allows the elements to expand and contract freely. No pins! The dense ceramic holders extend element life because they do not insulate the hot elements from the kiln interior.
Thermocouple Protection Tubes
Mullite protection tubes extend thermocouple life and keep kiln clean. The mullite protection tube keeps the metal oxides of the thermocouple tip from dropping off and contaminating your work.
Thick 8 Gauge Thermocouples
Thick 8 gauge thermocouples last a long time. Special Limit of Error to ANSI MC96.1 specifications is used.
Molded Ceramic Industrial-Grade Element Connection Blocks
Industrial grade ceramic terminal blocks make changing elements easy.
Proprietary Reflective Coating Hardens & Seals Brick
Special brick coating hardens and seals brick for durability and cleaner operation.
Extra Case Clamps
Three case clamps per 9" high kiln section are redundant safety for your L&L kiln.
Corrosion Resistant Case
Corrosion resistant materials and methods result in a long-lasting kiln.
Stainless Clips Secure Lids to Bands
Stainless Steel clips help the lid stay secure and durable. This extra step ensures that the lid won't slip out of the stainless steel band.
Strong Arched Sides with Extra Airspace (DaVinci)
Arched sides on DaVinci kilns are very strong and promote good air circulation
Steel Frame Supports Lid (DaVinci)
A unique welded rigid frame supports the entire lid on a DaVinci kiln.
Welded Angle Iron Stand (DaVinci)
Welded heavy-duty stand supports heavy loads. Alumized top sheet reflects heat.
