The components shown are basketball rims (hoops) and nets.
Rims are typically made of high tensile carbon steel, specifically a 5/8" (1.6 cm) diameter solid steel rod formed into an 18" (45.72 cm) inner diameter ring.
Many modern rims are "breakaway" style, featuring a hinge and spring mechanism that allows them to bend when pressure is applied, which improves safety and durability during dunks.
Nets are often made of durable nylon material designed to withstand various weather conditions.
The nets typically have 12 loops to fit standard-sized rims and a length of 15" to 18" (38.1-45.7 cm).
