Keep your Black & Decker bump-feed trimmer running without interruption with this KAKO ST4500-compatible spool set. Each spool arrives pre-wound with 20 feet of 0.065-inch polyamide nylon line and is molded from durable ABS so you can swap spools quickly and resume trimming. The kit includes 10 spools plus two caps and two springs to replace worn parts and get your unit back to factory-fit performance.

Which Black & Decker models will these spools fit?

These KAKO spools are cut and wound to match the dimensions and feed style of RS-136 family spools, so they are compatible with many Black & Decker bump-feed heads. Use them as direct replacements where the ST4500/RS-136 spool and cap form factor is required.

• Compatible models: ST4500, RS-136, GE600, CST800, ST1000, ST4000, ST6800
• Replaces spool models: RS-136 / RS-136-BKP / 143684-01
• Replaces cap and spring: cap 682378-02, spring 68223500

How durable is the line and what cutting conditions is it best for?

The line is made from high-strength polyamide nylon and the spool body from ABS plastic for resistance to impact and wear. It’s intended for light-to-medium vegetation such as young grasses and common yard weeds; thicker stems or heavy brush may require metal blades or heavier gauge line.

• Line diameter: 0.065 inches (suitable for bump-feed heads designed for this size)
• Length per spool: 20 feet, pre-wound for fast install
• Material: durable polyamide nylon line with ABS spool housing

How do I install a KAKO replacement spool in my Black & Decker trimmer?

Installation follows the same steps as the factory spool: remove the head cap, lift out the old spool assembly, place the pre-wound KAKO spool into the head, feed line ends through the eyelets, and reattach the cap and spring if needed. Always consult your trimmer manual for safety steps and correct reassembly order.

• Turn off and unplug battery/engine before servicing
• Match spool orientation and align feed eyelets before seating
• Use included caps and springs if originals are damaged or missing

What does the 10+2+2 pack include and are there any safety tips?

The set contains 10 pre-wound spools, 2 spare cap pieces, and 2 replacement springs so you have parts for multiple refills and a couple of hardware backups. Wear eye protection and gloves while handling line and during trimming; avoid using this line on dense, woody brush where it may break or become hazardous.

• Package: 10 spools + 2 caps + 2 springs (10+2+2 pack)
• Precaution: intended for light to medium vegetation only
• Support: contact seller by email if you have fitment or function questions

This KAKO kit is ideal if you prefer quick spool swaps, keep spare caps and springs on hand, and typically trim lawns, edges, and light weeds rather than dense brush or saplings.
