The 1421T8BK is a package of 24 small black square feet in the 1421-FEET Series. Each foot is 0.47 in (12 mm) wide and just 0.12 in (3 mm) high, a low-profile square foot for compact enclosures, desktop devices and tabletop products that need anti-skid feet without adding much height.

Attachment is self-adhesive, with Natural Rubber R-30 adhesive. The part page lists the material as rubber; the series data says the feet are made from polyurethane material, with the screw-on 1421T7 as the exception. The series service temperature rating is -34°C to 66°C (-30°F to 150°F).

For best adhesion results:

• Clean surfaces with isopropyl alcohol (rubbing alcohol)
• Apply firm pressure to generate good initial contact
• Expect the adhesion bond to increase over time

The 1421T8BK is RoHS compliant and REACH compliant, and the package ships at 0.03 lbs (0.01 kg). It is the smallest and lowest of the three square feet in the series; the 1421T3 is 0.50 in square and 0.23 in high, and the 1421T4 is 0.81 in square and 0.30 in high. Choose the 1421T8BK where clearance under the product is tight.
