## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-3410-0025-0112:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-3410-0025-0112:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The 25 tooth (H25T Spline) Servo-Mount Winch Pulley pulls its weight in cable-driven assemblies! Thanks to its 112mm circumference dual-spool design, it can simultaneously wind and feed out 112mm (4.4") of string per rev when two strings are attached opposite each other—an essential setup in power retract lifts and R/C sailboats. Attachment holes conveniently placed in both sides and troughs allow for multiple ways to tie up loose ends in pulley-based builds.
