YUNVI 10-Pack Stainless Steel Pool Cover Springs 7" with Vinyl Sleeves — 304 Stainless, 1.2" Ring

YUNVI's 10-pack stainless steel springs with vinyl sleeves is a ready-to-install replacement kit designed to secure pool covers, offering durable 304-grade corrosion resistance and protective vinyl sleeves for longer service life.

Whether you are replacing worn hardware on a seasonal pool cover or adding spare parts to a maintenance kit, these springs provide a straightforward, weather-resistant solution. Each kit contains ten 7" long springs with 1.2" ring openings and ten matching vinyl sleeves, sized to accept straps up to 1.2" wide. Built from 304 stainless steel, the springs resist rust and flex to engage cover straps, while the thicker vinyl sleeves reduce metal-on-strap wear and help keep the spring surface shielded from UV and chemicals.

How do these springs attach to my pool cover and anchor points?

The springs hook into cover straps and anchor points using the circular ends, delivering tension to keep the cover taut. Their 1.2" ring diameter fits most common pool cover straps, and the metal loops are designed for easy installation with standard cover hardware. The coil body stretches to add the needed give without overstressing the strap or anchors.

• 7" overall spring length with 1.2" ring opening for most straps
• Stretches up to approximately 8" to apply tension
• Fits standard cover anchors and buckle systems
• Includes ten sleeves to slide over coil contact points

Will these resist corrosion and outdoor exposure?

Constructed from 304 stainless steel, the springs are formulated to withstand moisture and outdoor conditions better than plain steel. The vinyl sleeves add an extra barrier against salt, chlorine, and UV rays, lowering the risk of early surface degradation. For longevity, rinse and inspect periodically, especially in highly chlorinated or salty environments.

• 304 stainless steel resists rust in typical pool environments
• Premium vinyl sleeves protect spring surfaces and straps
• Thicker sleeve material reduces abrasion and UV wear
• Recommended periodic cleaning for longest life

Are these springs compatible with other uses beyond pool covers?

Yes — these springs are universal replacement components suited to a variety of tensioning needs. Their durable coil and protective sleeve make them useful for trampolines, light mechanical fixtures, toys, and other outdoor gear that require flexible, corrosion-resistant connectors. Verify ring diameter and working length match your application before installing.

• Applicable to pool covers, trampolines, and light equipment
• Ring diameter holds straps up to 1.2" wide
• Compresses to about 7.5" for compact storage
• Ten-spring pack provides multiple replacements or spares

How much tension and movement can these springs handle?

The coils are engineered to stretch roughly to an 8" span under load, offering enough elasticity to absorb movement from wind or small shifts without disengaging. They compress to approximately 7.5" for storage when not in use. These springs are intended for moderate tensioning tasks rather than heavy industrial loads.

• Stretch capacity: about 8" for secure tensioning
• Compressed length: around 7.5" for compactness
• Designed for moderate, repeated flexing cycles
• Not meant for heavy industrial or high-load applications

Who is this for: This YUNVI 10-pack is ideal for pool owners, maintenance professionals, and DIYers who need a reliable, corrosion-resistant set of replacement springs and protective sleeves. It suits anyone replacing worn cover hardware, building a spare parts kit, or retrofitting straps on trampolines and light outdoor gear. If you require heavy-load rated springs or custom sizes, consider selecting specialized industrial components instead.
