Nexus Center Release Buckle Repair Kit for Hot Tub / Spa Straps 8 PACK — spa cover lock from SpaLocks. SKU NEX8816. Made in USA. $39.95.

For covers that open with a single push-button in the middle. Two keyed Nexus center-release locks plus screws, so the old straps stay in service.

Everything to rebuild two pinch-style latches in one bag: locks, keys, stainless screws, and strap adjusters. Keep the webbing, replace the hardware.

Sometimes only the clip half breaks. This kit replaces just that side (four male prong clips and four adjusters), so you keep your lock bodies and keys.

The budget fix for a two-latch cover: two SCL side-release locks and two keys. Hardware only, so you keep the straps you already have.

For covers with four locking points, or two straps that lock at both ends. Four SCL locks with keys, stainless screws, and adjusters. Straps not included.

One latch cracked and the rest are fine? This single SCL side-release lock replaces just that one: lock body, prong side, and a key. Your strap stays on the cover.
