Product Information
The Atomic Aquatics Spring Strap Assembly (MPN 05-0025-3P) is a stainless steel fin heel strap system for open heel scuba fins, built with rust-resistant springs and a variable pitch geometry that delivers a comfortable fit and easy one-hand removal. It fits Atomic fins and is available as a universal retrofit for many other open heel fin brands.
Who it is for
This assembly is for divers who want to replace worn rubber fin straps, or who are upgrading open heel fins to spring straps. It suits recreational and frequent divers working in rugged marine environments, where a strap that stays put through surf entries, boat ladders and long swims matters. Because the strap allows quick donning and doffing, it is also a practical choice for divers who gear up and de-kit repeatedly across a dive day.
Key details
- Material: rust-resistant stainless steel springs made for saltwater exposure.
- Design: variable pitch geometry heel spring that adapts to movement and supports a secure, custom feel.
- Operation: easy one-hand removal for quick donning and doffing.
- Fit: Atomic fins, plus universal retrofit on many other open heel fin brands.
- Part reference: MPN 05-0025-3P, UPC 882689089664.
Compatibility and sizing
Atomic Aquatics describes a Spring Strap Assembly as the strap system on its Open Heel HEC SplitFins; contact us to confirm part-level fit. Atomic's splitfins use the EZ-LOK patented buckle system (U.S. Patent #6,463,640), which releases from the fin with one hand and re-attaches securely. If you are fitting this strap to a non-Atomic fin, confirm your fin's buckle post style before ordering.

Frequently Asked Questions
Will the Atomic Aquatics Spring Strap Assembly fit non-Atomic fins?
It is made for Atomic fins and is also offered as a universal retrofit for many other open heel fin brands. Because buckle posts and heel pocket shapes differ between manufacturers, confirm your fin's buckle style before ordering. If you are unsure, call DiveCatalog at 888-701-4017 with your fin make and model and we can check compatibility with you.
Why choose spring straps over standard rubber fin straps?
The stainless steel spring strap automatically adjusts to depth and movement for a secure, comfortable fit. The adaptive stainless steel spring strap automatically adjusts to depth and movement for a secure, custom fit. It allows one-hand removal so you can don and doff fins quickly on a boat or at the shoreline. The rust-resistant stainless construction is also built for repeated saltwater exposure.
What is the part number for this strap assembly?
The manufacturer part number is 05-0025-3P and the UPC is 882689089664. Quote the MPN when you contact us so we can match the correct assembly to your fins.
How do the straps attach to Atomic open heel fins?
