Ideal for

  • Fastensol GS Roof rail runs that need rail sections joined
  • Installers matching the F-RS-S LAMPS SKU to the F-RC-S Fastensol rail connector reference
  • PV arrays where rail length exceeds one rail section
  • Roof-mounted solar projects using compatible Fastensol rail profiles

Works well with

  • Fastensol F-MR-S-3.5 F-MR3550 3550mm silver mounting rail
  • Fastensol F-TH01 TH01 pantile hooks
  • Fastensol F-TH02 TH02 flat tile hooks
  • Fastensol TH04 slate hooks
  • Fastensol F-UC-B UC-GS universal clamps for 30-46mm framed modules

The Fastensol F-RS-S silver rail splice, manufacturer article F-RC-S, is a 200mm connector for joining compatible Fastensol mounting rail sections in PV roof systems.

  • LAMPS sellable SKU F-RS-S and Fastensol article F-RC-S
  • Silver rail connector for Fastensol mounting rail
  • 200mm length listed by Fastensol
  • 0.1kg weight listed by Fastensol
  • Pre-assembled rail connector
  • Material listed as Al6005-T5 aluminium and stainless steel 304
  • Surface treatment listed as anodised

Why use F-RS-S or F-RC-S?

F-RS-S is the LAMPS sellable SKU, while F-RC-S is the Fastensol article reference for the silver rail connector. Both codes should be kept in the description because installers may search for either depending on the supplier paperwork, project take-off or Fastensol drawing.

The splice should be used as a Fastensol system connector, not as a generic rail joiner. Its purpose is to connect compatible rail sections so the installer can create the required rail length for the module row.

How does a rail splice affect the layout?

The splice becomes part of the rail run between roof fixings and module clamps. Its position should be planned with the rail span, module width, roof fixing spacing and any rail overhang shown in the mounting design.

Longer module rows may need multiple rail lengths joined together. Shorter runs may require cutting the rail and finishing the exposed end with a compatible cap. The splice should be installed only where the system layout allows it.

What materials are listed?

Fastensol lists Al6005-T5 aluminium and stainless steel 304 for the rail connector, with an anodised surface treatment. The connector is listed as pre-assembled and 200mm long, with a verified weight of 0.1kg.

The silver finish makes this the matching connector for silver rail runs. If the project uses a different finish, check the specified Fastensol rail connector version before ordering.

What should it be ordered with?

Use F-RS-S with compatible Fastensol mounting rail, roof hooks or slate brackets, universal clamps and rail end caps where required by the project. Browse Fastensol GS Roof or the full solar mounting systems range for related products.

Is F-RS-S the same as F-RC-S?

F-RS-S is the LAMPS sellable SKU. F-RC-S is the Fastensol article reference for the silver rail connector.

How long is the rail splice?

The Fastensol datasheet lists the rail connector as 200mm long.

What is the verified weight?

The Fastensol datasheet lists the connector weight as 0.1kg.

What warranty terms apply?

Fastensol documentation states a 12-year limited product warranty and 5-year limited finish warranty, subject to correct installation and the manufacturer’s terms.
