STASIŃSKI electrical trunking spacer R-90 for 90 mm cable ducts, single piece

STASIŃSKI R-90 is a single-piece electrical trunking spacer engineered for cable ducts with a 90 mm internal width. It is intended to hold and position mounting strips or rails inside the duct, enabling orderly cable runs and consistent separation between conductors. The spacer is compatible with common electro-installation profiles used in residential and commercial wiring systems and is designed to fit securely within 90 mm cable trunking.

Advantages

The single-piece construction provides stable fixation of mounting strips without additional fasteners, reducing installation time. Its shape ensures reliable alignment of rails and strips inside the trunking, which helps maintain clear separation of cable groups and improves access for later maintenance. The spacer is suited for repeated use in typical low-voltage installations and is made to integrate with standard 90 mm ducts used in building wiring.

Suitable for

• Organizing power and data cables inside 90 mm electrical trunking
• Securing mounting strips or small rails within cable ducts
• Residential and commercial electrical installations requiring internal separation
• Retrofit or new-build projects where a durable spacer for 90 mm ducts is needed

Key specifications

• Designed for cable ducts with 90 mm internal width
• Single-piece spacer for internal trunking use
• Intended to position and secure mounting strips or rails
• Compatible with standard electro-installation profiles used in buildings

How to use

Insert the spacer into the 90 mm cable duct at the desired position along the run, aligning it so that mounting strips or rails can be fitted into the spacer's guide points. Ensure the spacer sits flush inside the duct and that any attached strips are held securely. Multiple spacers can be placed at regular intervals to maintain consistent support and separation throughout the duct length. No special tools are required for basic placement, though standard trunking assembly tools may be used to fix adjacent components.

Usage recommendations

Position spacers at intervals appropriate to the weight and type of cables used; for heavier or bundled cables, reduce spacing between spacers. Verify compatibility with the specific trunking profile before installation and follow applicable local electrical codes and standards during mounting and cable routing.
