- Electrical capacity (amp/voltage ratings and motor HP support)
- Ease of installation and wiring clarity
- Feature set (mechanical scheduling, digital 7‑day programming, Wi‑Fi/smart controls)
- Real‑world performance: set schedules, measured repeatability, and observed behavior after power cycles
- Value: feature-to-price balance and availability of replacement parts
Sources
- Hands‑on bench testing and outdoor installations on pool circuits
- Cross‑referenced manufacturer specs (ETL/UL listings, IP/NEMA ratings)
- Analysis of hundreds of user reviews to spot common failure modes and praised features
We weighted safety, electrical capacity, and weatherproofing highest, then connectivity and programmability. For replacement trippers we focused on fit/compatibility and corrosion resistance.
Pool Timer Tripper Kit
A minimal, inexpensive pack of replacement tripper clips and screws for Intermatic T100-series timers. Lightweight, corrosion‑resistant material and longer screws make quick on‑dial adjustments possible without replacing the whole timer. Great for simple repairs and fine tuning.
Why we picked it (Budget)
This 4‑piece tripper kit is a fast, inexpensive way to restore or tweak an Intermatic T100‑series dial timer. Built from corrosion‑resistant metal and supplied with longer fixing screws, the kit installs in minutes and keeps a working mechanical timer in service without replacing the whole box. It won’t add smart features or extra load capacity, but for many pool owners a replacement tripper is all that’s needed to regain precise on/off positions. Pros: lowest cost, correct fit for many Intermatic models, longer screws. Cons: not a complete timer — only useful if your existing clock/dial mechanism is still functional.
DEWENWILS Heavy-Duty Timer
