Start with the whole Cilindro installation
Give your 10.5 kW Cilindro Half a warm, curved birch surround. Four wooden arches and stainless steel mounts create a defined boundary around the hot heater. Warm-white LED lighting shines down from the rail toward the heater.
HPCU4LUL is for compatible U.S. 10.5 kW Cilindro Half heaters. Use the smaller accessory for 6, 8 or 9 kW models.
1. Choose the heater
Match the Cilindro to your sauna volume, glass surfaces, available power and control preference.
2. Plan the bench
Decide whether the heater stands beside the bench or passes through it. Keep access for installation and maintenance.
3. Finish the details
Choose a size-matched flange, railing and lighting. Each accessory is sold separately.
What the HPCU4LUL adds
- Four curved heat-treated birch sections with stainless steel mounts.
- 20.5 in overall railing width.
- Attaches to the heater with the specified mounting hardware.
- 3000–3200 K warm-white LED lighting.
- 100–240 V supply with 12 V DC lighting output; connection by a licensed electrician.
Plan the installation
Mount the rail to the heater as shown in its installation guide. Keep the heater’s required clearances and service access. A rail helps define the hot-heater area; it does not make the heater or stones safe to touch.
Heater, control, stones, embedding flange and bench timber are separate.
Questions before you choose
Which Cilindro does it fit?
HPCU4LUL is for compatible U.S. 10.5 kW Cilindro Half heaters. Use the smaller accessory for 6, 8 or 9 kW models.
Is the heater included?
No. This listing is for the HPCU4LUL led safety railing. Heater, control, stones, embedding flange and bench timber are separate.
Can I see it installed?
Yes. Open the 3D viewer, rotate the assembly and try the bench and raised-platform views. The bench-height slider and cutaway show how the installation fits together. The visualization is for planning; use the manuals for construction.
Do I need a flange and a railing?
They serve different jobs. An embedding flange finishes and shields a bench opening; a railing creates a wood boundary around the heater. The 3D railing bench views include a separate flange to show that combination.
What should I plan before installation?
Mount the rail to the heater as shown in its installation guide. Keep the heater’s required clearances and service access. A rail helps define the hot-heater area; it does not make the heater or stones safe to touch.
How does the lighting work?
The warm-white LEDs face down beneath the wood rail. The power supply and cable route must follow the installation guide. A licensed electrician must make the electrical connection.
Make the heater the starting point.
Choose your Cilindro, then build the accessory package around the sauna you want.
