The DS21A-P-BLK through-hull can accommodate connectors with a maximum diameter of Ø21 mm.

This deck gland is designed for cables with diameters ranging from 4 mm to 9 mm.

No, the DS21A-P-BLK cable gland is specifically designed for cables with a diameter between 4 mm and 9 mm. For 10 mm cables, consider a different model such as the DS21B, which supports cables from 9 to 14 mm.

The DS21A and DS21B models share the same connector drilling diameter (Ø21 mm) and the same external dimensions. The main difference lies in the cable diameter range they can accommodate: the DS21A is for 4–9 mm cables, while the DS21B is for larger 9–14 mm cables.

Yes, although it is designed to facilitate the passage of connectors, it can also be used for cables without connectors, provided the cable diameter is between 4 mm and 9 mm and you use the appropriate bung.

Yes, silicone should be used to ensure optimal watertightness during deck gland installation and prevent water ingress.

You must select the bung supplied in the kit whose inner diameter is closest to that of your cable. The DS21A kit includes several bungs to cover the cable diameter range from 4 to 9 mm.

Recommended pilot hole sizes for screws depend on the material of your mounting surface:

For soft materials (such as plywood): Ø2.5 mm (3/32 in)For hard materials (such as acrylic, hardwoods): Ø3 mm (1/8 in)

Yes, it is advisable to freeze the bung before drilling it. This will make the material more rigid and facilitate a clean cut.

The DS21A-P-BLK cable gland is designed for passing a single cable with a connector at a time, using the bung adapted to the diameter of that single cable.
