ProSlam 180° Heavy Duty Breakaway Basketball Rim, 2-Double spring, 18" 5/8" Solid Steel Positive Lock

ProSlam 180° Heavy Duty Breakaway Basketball Rim is an 18-inch double-spring replacement rim built from 5/8" solid steel that flexes a full 180° and returns to position with a positive lock, compatible with four standard backboard hole patterns.

This heavy-duty replacement rim is engineered for players who demand durability and reliable dunk performance without compromising the backboard. Designed to fit common mounting hole configurations, the ProSlam rim includes an all-weather nylon net and full installation hardware so you can swap it in quickly. The thicker steel, dual-spring breakaway action, and positive locking mechanism make it suitable for backyard courts, school gyms, and community play areas where aggressive play happens regularly.

How does this rim handle powerful dunks and repeated impact?

The ProSlam rim uses a double spring system that allows the hoop to flex downward a full 180° under load, then instantly return to true horizontal thanks to its positive lock. That controlled flex reduces strain on the frame and backing while maintaining a responsive feel for players. Built from 5/8" solid alloy steel, it resists bending, warping, and metal fatigue much better than thinner models.

• Double-spring breakaway action for controlled flex and reliable rebound.
• Positive lock returns rim to exact horizontal position after each dunk.
• 5/8" solid steel construction reduces chance of bending or failure.
• Durable finish helps resist corrosion in outdoor settings.

Will this fit my existing backboard or hoop mounting pattern?

ProSlam is made to accommodate four common hole patterns — 5"x5", 5"x4", 4"x3" and 5"x3" — so you can match it to many major backboard systems. Before ordering, measure the spacing of the mounting holes on your backboard to ensure a snug, aligned installation. The package includes the bolts, nuts, and washers needed for secure mounting to most compatible frames.

• Compatible hole patterns: 5"x5", 5"x4", 4"x3", 5"x3".
• Includes full mounting hardware for fast installation.
• Measure hole spacing first to confirm fit with your backboard.

What comes in the box and how easy is installation?

The rim arrives ready to install with an industrial-grade 169g nylon net and all necessary mounting hardware. Installation is straightforward for anyone familiar with changing a rim: align the bolt holes, secure the rim with the supplied bolts and washers, and tighten to the recommended torque. The included net is weather-resistant so you won’t need to buy extras for outdoor use.

• One 18" orange breakaway rim with positive lock mechanism.
• Heavy-duty 169g all-weather nylon net included.
• Bolts, nuts, and washers provided for typical backboard mounts.

How does this rim protect my backboard and extend hoop life?

By letting the rim move under load, the dual-spring design dissipates the energy from dunks and hard rebounds instead of transferring it into the backboard and support structure. That reduced stress lowers the risk of cracks, loose hardware, or warped mounting plates over time. The sturdier 5/8" steel tube also maintains structural integrity far longer than thinner rims, decreasing repair frequency.

• Breakaway flex absorbs impact energy before it reaches the backboard.
• Positive lock prevents sagging that can stress mounting points.
• Thick steel tube reduces long-term wear and potential damage.

Who is this for? ProSlam’s 180° Heavy Duty Breakaway Rim is aimed at competitive players, recreational dunkers, and facility managers who need a robust, reliable hoop upgrade. If you want a durable replacement that fits common mounting patterns, supports heavy play, and arrives with everything required to mount and use immediately, this rim is an efficient, long-lasting choice.
