The 1421T2 is a package of 24 black flat round rubber feet from the 1421-FEET Series. Each foot is 0.50 in (13 mm) in diameter and 0.14 in (4 mm) high, with a self-adhesive backing, making it a low-profile anti-skid foot for small cases, desktop equipment and tabletop devices.

The attachment method is self-adhesive, and the adhesive type is Natural Rubber R-30. The part page lists the material as rubber, while the series data states the feet are made from polyurethane material (the 1421T7 is the one exception, made from SBR rubber). The series service temperature rating is -34°C to 66°C (-30°F to 150°F).

For best adhesion, the manufacturer recommends:

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

The 1421T2 is RoHS compliant and REACH compliant, and the package has a shipping weight of 0.04 lbs (0.02 kg). The same 0.50 in flat round style also comes in clear (1421T2CL) and gray (1421T2GY).

Among the black self-adhesive feet in the series, the 1421T2 sits between the smaller 0.47 in square 1421T8BK and the taller 0.50 in square 1421T3, giving a flat, low-height round foot for products where clearance under the case is limited.
