Other Products ｜10" Hand Cup With Low-Marking Pad For Curved Surfaces

Wood's Powr-Grip N6450LM — 10" Metal Handle Vacuum Hand Cup with Low-Marking, UV-Resistant Pad for Curved Nonporous Surfaces (175 lbs / 79 kg)The Wood's Powr-Grip N6450LM is a 10" vacuum hand cup specifically designed to lift curved nonporous surfaces without leaving any mark or stain behind, featuring a Low-Marking, UV-Resistant rubber pad that combines two specialized rubber compounds in one pad. Rated for loads up to 175 lbs (79 kg) on curved and flat smooth, nonporous surfaces. Features a durable metal handle and comes with a protective carrying case. Not for use on thin or fragile materials — minimum material thickness 1/4" (6.35 mm). The N6450LM (SKU: 91804, Model: N6450LM) is manufactured by Wood's Powr-Grip.The N6450LM is the Low-Marking variant of the N6450 hand cup family, using a specialized rubber compound that will not mark or stain most surfaces during lifting — making it the correct choice for polished stone, finished architectural surfaces, and other materials where standard rubber pad contact marks are unacceptable. The UV-Resistant compound in the same pad extends service life in outdoor and UV-exposed environments. The N6450LM is primarily designed for curved surfaces; it also attaches to flat surfaces but requires more pumping than hand cups specifically designed for flat surfaces (such as the N6450 or N6300).Key Features & BenefitsLow-Marking Rubber Compound — Will Not Mark or Stain Most SurfacesThe N6450LM’s Low-Marking rubber compound is specifically formulated to not leave marks, stains, or residue on most surfaces during lifting — the critical differentiator from standard rubber pads, which can leave contact marks on polished stone, finished architectural surfaces, and other sensitive materials. This makes the N6450LM the correct choice for applications where surface marking is unacceptable, including polished granite and marble countertops, finished architectural glass, and other high-value surfaces where pad contact marks would require remediation. See the WPG Rubber Compounds and Applications guide for surface compatibility details.UV-Resistant Rubber Compound — Extended Outdoor Service LifeThe N6450LM pad also incorporates a UV-Resistant rubber compound, providing extended service life in outdoor and UV-exposed environments where standard rubber pads would degrade from sunlight exposure. This dual Low-Marking + UV-Resistant compound makes the N6450LM suitable for outdoor applications on polished stone, architectural glass, and other UV-exposed surfaces where both marking prevention and UV resistance are required. See the WPG Rubber Compounds and Applications guide for details.Curved Surfaces Primary — Also Attaches to Flat (More Pumping Required)The N6450LM is primarily designed for curved nonporous surfaces — including curved architectural glass, curved stone panels, and curved metal surfaces. It also attaches to flat surfaces, but requires more pumping than hand cups specifically designed for flat surfaces (such as the N6450 or N6300). If your application is primarily flat surfaces, the standard N6450 or N6300 with Low-Marking pad may be more appropriate.175 lb (79 kg) Capacity — Metal Handle — Protective Carrying CaseRated for loads up to 175 lbs (79 kg). Features a durable metal handle for heavy-duty lifting. Comes with a protective carrying case — not pad protectors — keeping the cup protected during transport to and from job sites. Red-line indicator warns of any significant vacuum loss.Minimum 1/4" Material Thickness — Not for Thin or Fragile MaterialsNot for use on thin or fragile materials — minimum material thickness is 1/4" (6.35 mm). Vacuum pressure can cause thin or fragile materials to fracture even at the 1/4" minimum thickness if the material is inherently fragile. Always confirm material thickness and structural integrity before use.Common ApplicationsPolished Stone — Granite, Marble, and Engineered StoneStone installers and fabricators handling polished granite countertops, marble panels, and engineered stone use the N6450LM where standard rubber pads would leave contact marks on the polished surface. The Low-Marking compound prevents pad marks on finished stone surfaces, and the curved surface rating covers the range of stone panel curvatures encountered in architectural and countertop installation.Curved Architectural GlassGlaziers handling curved architectural glass panels use the N6450LM where the curved surface rating and Low-Marking compound are both required — curved glass that cannot be marked by the lifting cup during installation.Outdoor Curved Surface LiftingThe UV-Resistant compound makes the N6450LM suitable for outdoor lifting applications on curved smooth nonporous surfaces where both UV resistance and marking prevention are required.High-Value Finished SurfacesAny curved nonporous surface where standard rubber pad contact marks are unacceptable — including finished architectural surfaces, high-gloss panels, and other sensitive materials within the 175 lb capacity and 1/4" minimum thickness requirements.N6450 Family — Pad Compound Comparison

Frequently Asked QuestionsQ: What is the difference between the N6450LM and the standard N6450?A: Both are 10" curved surface hand cups rated for 175 lbs with metal handles. The N6450LM uses a Low-Marking, UV-Resistant rubber compound that will not mark or stain most surfaces and provides UV resistance for outdoor use. The standard N6450 uses standard rubber. Choose the N6450LM when surface marking is unacceptable (polished stone, finished architectural surfaces) or when UV resistance is required for outdoor use; choose the standard N6450 for general curved surface lifting where marking is not a concern.Q: Can the N6450LM be used on flat surfaces?A: Yes, but it requires more pumping than hand cups specifically designed for flat surfaces (such as the N6450 or N6300 flat-surface variants). If your application is primarily flat surfaces, a flat-surface-specific hand cup will be more efficient.Q: What does “Low-Marking” mean in practice?A: The Low-Marking rubber compound is formulated to not leave contact marks, stains, or residue on most surfaces during lifting. Standard rubber pads can leave circular contact marks on polished stone, finished glass, and other sensitive surfaces — particularly after extended contact or in warm conditions. The Low-Marking compound significantly reduces this risk. See the WPG Rubber Compounds and Applications guide for surface-specific compatibility details.Q: Is this product made to order?A: Yes. This product is made to order and all sales are final. Please confirm your surface type, curvature, material thickness, and marking sensitivity requirements before placing your order.WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm.
