Coverage where hits land
Knuckle bridge plus finger segments, with an optional thumb guard. We shape the TPR to the liner so it stays put when the hand flexes instead of riding up.
ANSI/ISEA 138 · TPR back-of-hand
TPR armor across the knuckles and fingers for struck-hand injuries, without turning the palm into a brick.
Impact-resistant work gloves target the back of the hand: knuckles against a beam, fingers caught between a pipe and a flange. A cut-resistant liner does nothing for that. The fix is a molded TPR (thermoplastic rubber) guard stitched over the knuckles and finger backs, shaped so it deflects rather than concentrates the hit.
The design tension is real. More coverage protects more, but it also traps heat and reduces finger bend. We build impact gloves in three coverage levels and pair them with palm options from thin PU to sandy nitrile, so the glove still works for the task that caused the hazard.

Knuckle bridge plus finger segments, with an optional thumb guard. We shape the TPR to the liner so it stays put when the hand flexes instead of riding up.
Impact protection is only useful if the glove can hold the tool. Palm options run from thin PU for control to sandy nitrile for oily steel, with a reinforced thumb crotch on heavy builds.
Pair the TPR shell with an A3–A5 HPPE liner when the job also involves sharp edges. One glove, two hazards, instead of layering two pairs.
Reference
Ratings depend on liner, gauge and coating. Final values are confirmed on the approved sample.
Higher levels add protection and weight. Match the level to the struck-hand risk, not to the heaviest option available.
| Level | Coverage | Typical build | Where it fits |
|---|---|---|---|
| 1 | Knuckle bridge | Light TPR on knit liner | Maintenance, light assembly |
| 2 | Knuckle + finger backs | Segmented TPR, reinforced palm | Construction, rigging, HVAC |
| 3 | Full back + thumb | Heavy TPR, leather or nitrile palm | Heavy steel, demolition, oil and gas |
Questions buyers ask
If your question is about a specific style, send the spec and we will answer with the sample plan instead of a generic reply.
Only if the liner is cut-rated. The TPR shell handles impact; the liner handles cuts. Specify both — an A4 liner under a level 2 TPR shell is a common construction combination.
It adds coverage, so it traps some heat. We use vented TPR segments and open-back liners on warm-weather styles, and can quote a lighter level 1 shell if heat is the deciding issue.
Yes, conductive fingertips can be added to thumb and index. On heavy TPR builds the fingertip pad stays thin, so the touch function still works.
500 pairs per style and color. The TPR mold is shared across our standard shapes; a fully custom mold carries a separate tooling cost and longer lead time. For a repeat programme, that tooling is usually absorbed on the first reorder.
