Blind cover Rittal SK 3237.021 for 1" (2.54 cm) display, anthracite, pack of 2

Rittal SK 3237.021 blind cover is a purpose-made panel insert for closing unused 1" (2.54 cm) display openings in enclosures and control panels. Supplied as a pack of two in anthracite, the cover fits mounting openings compatible with the Rittal SK series and provides a flush, dust-reducing closure that helps maintain the enclosure’s internal environment.

Advantages

The blind cover offers a clean, uniform appearance for panels with vacant display cutouts and reduces the risk of dust and foreign objects entering the enclosure. Its standard 1" size ensures compatibility with equipment designed for Rittal SK series openings, and the anthracite finish integrates discreetly with many industrial and commercial housings. Supplied in a two-piece pack, it supports multiple closures or spares for maintenance.

Suitable for

• Closing unused 1" (2.54 cm) display cutouts in control panels and switchgear
• Protecting internal components from dust and contamination where displays are not installed
• Standardising panel appearance in industrial cabinets and machine housings
• Replacement or spare part use during equipment servicing

When it may not be suitable

This blind cover is intended specifically for 1" (2.54 cm) display openings compatible with the Rittal SK series. It may not fit non-standard or proprietary cutouts that differ in dimension, mounting profile, or retention method. The product provides a passive closure and does not offer features such as sealing to IP ratings beyond typical panel-mounted covers, so it may not meet requirements where high ingress protection or environmental sealing is mandatory.

Key specifications

• Colour: anthracite
• Intended cutout size: 1" (2.54 cm)
• Pack contents: 2 pieces
• Mounting type: panel insert for compatible Rittal SK series openings

How to use

Place the blind cover into the matching 1" display opening on the enclosure front panel and engage according to the panel’s mounting profile; the part is designed to seat flush in compatible Rittal SK series cutouts. For secure installation align the cover edges with the cutout and press until it locks or rests evenly. If used as a replacement, remove the existing insert first and check the opening for burrs or debris before inserting the new cover. No special tools are usually required, though a soft implement can help seat the part without scratching the finish.

What to consider before purchase

• Confirm the display cutout dimensions are 1" (2.54 cm) and that the panel uses Rittal SK series-compatible mounting.
• Verify the anthracite colour is acceptable for your panel aesthetic or marking needs.
• Consider whether an IP-rated sealed blanking plate is needed for higher environmental protection.
• Ensure a two-piece pack meets your quantity requirements or plan for additional units if needed.

Usage recommendations

Use the blind cover to maintain a tidy panel layout and reduce dust entry where a display is not required. Inspect the fit after installation and keep spare covers available for maintenance to ensure consistent protection of internal components.
