Two black plastic trimmer head bump knob covers for T25

LAHDEK Trimmer Head Bump Knob Cover T25 2pcs 537338701

SKU CH-R5PV-17MYY

Two-pack bump knob covers replace OEM 537338701 on Husqvarna T25 petrol trimmer heads

  • Fits Husqvarna T25 trimmers for reliable line feeding
  • Replaces OEM part 537338701 ensuring correct fit
  • Two-pack provides a spare for continuous work
  • Designed for petrol two-stroke trimmer heads
  • Durable construction withstands regular bump-feeding use

LAHDEK T25 Bump Knob Cover Pair

This two-pack supplies replacement bump knob covers for Husqvarna T25 trimmer heads. Each cover fits the OEM part numbered 537338701 on petrol-driven two-stroke models. Homeowners and landscaping crews can keep a spare on hand for quick field swaps.

Direct fit for T25 heads, two per pack

The covers match the original T25 specification so line advance works as designed. Two pieces give enough headroom for a full season of edging and trimming on a single machine. They do not fit other trimmer head models or electric units.

Replaces worn or cracked OEM knob covers

Swapping the cover restores reliable line feed when the original becomes brittle or strips its threads. The upgrade is worth it whenever the bump action feels loose or line stops advancing. Buyers needing parts for non-T25 heads or battery-powered trimmers should look elsewhere.

Questions about this item

Will the T25 bump knob cover fit the trimmer head I already use on my petrol brushcutter?

The cover is made as a direct replacement for the Husqvarna T25 trimmer head and matches OEM part 537338701, so it installs on that head without modification.

How can I confirm the new cover is seated correctly once I snap it on?

After fitting, the knob should rotate freely and the line must advance cleanly when you tap the head on the ground during operation.

Does the pack contain two complete covers or do I need to buy springs or screws separately?

The package includes two trimmer head bump knob covers only; no springs, screws or other hardware are supplied.
