- ASTM F1505 tested insulation ensures verified dielectric safety
- Dual orange and yellow layers provide visual wear indication
- 3/8" drive fits standard sockets for versatile use
3/8" Drive 42 Tooth Insulated Ratchet Head
This 3/8" drive ratchet head is built for electrical professionals who need verified insulation on live circuits up to 1000 V. The 42 tooth mechanism provides fine incremental engagement in tight enclosures. It meets ASTM F1505 testing requirements and carries the California Proposition 65 notice for listed chemicals.
Insulation Limits and Visual Indicator
The dual layer insulation uses an orange outer layer over a yellow inner layer that acts as a visual safety indicator. If the yellow layer becomes visible the tool must be removed from service because the insulation integrity is compromised. The 1000 V rating applies only while the insulation remains intact and the tool is used within its tested scope.
Replaces Non Insulated Ratchet Heads
This head replaces standard non insulated 3/8" ratchet heads when work must be performed on or near energised components. The upgrade is justified whenever a risk assessment calls for insulated hand tools rated to 1000 V and tested to ASTM F1505. It is not suited for applications that require a larger drive size or higher torque capacity than the 3/8" format provides.

Questions about this item
Which drive size and tooth count should I select for this insulated ratchet head?
This model is a 3/8" drive with a 42-tooth mechanism; no other drive sizes or tooth counts are offered for the 20842-I.
What does the 1000 V rating mean when I use the ratchet on live equipment?
Each head is individually tested to ASTM F1505 and provides user protection up to 1000 V; the orange outer layer and yellow indicator layer show insulation integrity at a glance.
How does the ASTM F1505 standard apply to this 3/8" drive ratchet head?
The standard governs the 1000 V insulation testing and the dual-layer visual safety indicator, confirming the head meets the required dielectric protection for live electrical work.
