Kling Dressing for Wound: What Conforming Gauze Is and Is Not

A Kling dressing is a stretchy roll of gauze that wraps around a limb or a pad. “Kling” is a brand name; the product class is a conforming bandage. Who uses it: clinic and first-aid staff, supply buyers and students comparing wound-care materials. After reading, you should be able to tell which regulatory category a conforming bandage falls into, read the size on a label, and know what a wet-to-dry dressing is.

What is a Kling (conforming gauze) bandage?

A Kling-type bandage is a conforming roll bandage: a roll of stretchable material sold under names such as “conforming bandage” or “conforming gauze.” This page uses “Kling-type” for the class and does not describe any one brand’s specification. In FDA records, many of these rolls are listed as single-use devices, some sterile and some non-sterile.

The same name covers products that FDA files under different rules, which is the most useful thing to know before comparing labels (see the next section). For the broader family, see the CASRAI guides on bandages, elastic bandages and wound dressings.

Kling bandage vs elastic bandage vs antimicrobial conforming bandage: FDA categories

Products sold as a “conforming bandage” are not all the same kind of device. In FDA’s UDI database (queried 2026-11-01) they appear under at least three product codes, depending on material and added ingredients.

Product code	FDA name	Regulation	Class	Example conforming-bandage records
NAB	Gauze / sponge, nonresorbable, for external use	21 CFR 878.4014	I (general controls); exempt from 510(k)	Cardinal Health conforming bandage gauze, sterile; McKesson conforming bandage, sterile
FQM	Bandage, elastic	21 CFR 880.5075	I (general controls); exempt from 510(k)	Derma Sciences non-sterile and sterile conforming bandages
NYS	Wound dressing with an antimicrobial added (PDADMAC)	21 CFR 878.4015	II (special controls); not the 510(k)-exempt Class I of NAB and FQM	Derma Sciences Bioguard conforming bandage

What the rules say. 21 CFR 878.4014 describes nonresorbable gauze as a strip, piece or pad of open woven or nonwoven cotton cellulose or a simple cellulose derivative, typically placed directly on a wound to absorb exudate, and it excludes versions with added drugs such as antimicrobials. 21 CFR 880.5075 describes an elastic bandage as a long flat strip or a tube of elasticized material used to hold snugly and apply pressure. So a roll labelled “conforming” may be a gauze under NAB, an elastic bandage under FQM, or an antimicrobial dressing, and the label alone does not say which. The antimicrobial variant under NYS is classified separately (21 CFR 878.4015, Class II per FDA’s product classification database, checked 2026-11-01), so it is not exempt from 510(k) the way the plain gauze and elastic bandage listings are.

Sizes in FDA UDI records

Labelled sizes below are copied from device descriptions in FDA’s UDI records (checked 2026-11-01). Note the length conventions: some labels give a stretched length in yards, others a relaxed length in inches.

Labelled size	Sterility on label	Length basis	Product code	Record source
2, 3, 4 and 6 in x 75 in	Sterile	As labelled (inches)	NAB	Cardinal Health
6 in x 4.1 yd	Sterile	As labelled	NAB	McKesson
2, 3, 4 and 6 in x 4.1 yd	Non-sterile	Stretched	FQM	Derma Sciences
2, 3, 4 and 6 in x 4.1 yd	Sterile	Stretched	FQM	Derma Sciences
3 in and 6 in x 145 in	Non-sterile	Relaxed	FQM	Derma Sciences
2, 3 and 4 in x 4.1 yd	Sterile (antimicrobial variant)	Stretched	NYS	Derma Sciences Bioguard

Because 4.1 yd stretched and 145 in relaxed are different bases, two rolls with different numbers on the label can be a different measurement rather than a different amount of material.

What is a wet-to-dry wound dressing?

Wet-to-dry is the name given to a gauze-based dressing approach. A 2009 review in Eplasty (Lee, Kandula and Sherber, “Beyond Wet-to-Dry”) states that “Wet-to-dry and gauze dressings remain the most widely used primary dressing material in the United States.” Gauze rolls such as conforming bandages are gauze-based, which is why the two are often discussed together. How any dressing is applied or changed is a matter for a clinician’s instructions and the product’s own labelling.

What is an Adaptic wound dressing?

Adaptic is a non-adhering oil emulsion dressing, a different product from a gauze roll. CASRAI covers it in What Is Adaptic?.

Common mistakes

• Treating “conforming bandage” as one product. FDA records place such rolls under gauze, elastic bandage and antimicrobial dressing codes.
• Comparing sizes without checking whether the length is stretched or relaxed.
• Assuming every roll is sterile. The UDI records above include both sterile and non-sterile rolls.

FAQ

What is a Kling bandage?

Kling is a brand name for a conforming roll bandage. The generic class is a conforming bandage, and in FDA records such products appear as gauze (NAB) or elastic bandage (FQM) devices depending on material.

What is a conforming bandage?

A conforming bandage is a stretchable roll bandage. FDA classes plain gauze (21 CFR 878.4014) and elastic bandages (21 CFR 880.5075) as Class I devices exempt from 510(k), subject to the limitations in the regulations.

Is a Kling dressing the same as an elastic bandage?

Not necessarily. Some conforming bandages are filed as gauze (NAB), others as elastic bandages (FQM); see the table above. Related reading: the Robert Jones bandage, which uses a conforming layer, and the wound care supply selection guide.
