Why Choose Our Door and Window Sliding Supports?
- Our door and window sliding hardware uses a slotless snap-fit structure, eliminating the need for pre-milling grooves in the frame and sash; it directly snaps on.
- Simply insert it into the profile slot and secure it with screws; this can save you time on your project.
- Available in left-hand and right-hand opening configurations, making it easy to install correctly. The side-opening design and clear top overhang are easily distinguishable, and it works well with our JD005 support and JFZ.
- The anti-detachment device and the complete set of hardware are installed without error.
- We support custom-made non-standard door and window sliding supports. Our professional technical team will provide free selection advice based on your project and window type.
- The matching system accurately recommends slotless and conventional sliding supports based on the profile groove, reducing the cost of selection errors.

Professional Door and Window Skid Support Supplier
Verixor has been deeply involved in the door and window sliding support industry for many years and understands the problems faced by project purchasers, general contractors, door and window manufacturers, and hardware wholesalers, such as rusted door and window sliding supports, stuck opening and closing, doors and windows not closing tightly, and insufficient load-bearing capacity leading to window sash sagging.
Our door and window sliding supports are made of SUS304 stainless steel, with key load-bearing parts thickened by 3.0mm. They are integrally stamped and formed without seams. The sliding supports undergo salt spray passivation anti-corrosion treatment, ensuring they will not rust or jam in humid, coastal, or rainy environments. They have a self-positioning force of ≥40N, preventing them from opening by wind, and can withstand 1500N of external force when closed, resisting typhoons and wind pressure. They have also passed 35,000 repeated opening and closing tests, with a gap of less than 1.5mm after repeated opening and closing, ensuring they will not sag or fail to close properly even after long-term use.
Our technicians design load-bearing gradients based on a safety factor of 1.3 (window weight). For small residential windows, we offer lightweight, groove-free sliding supports weighing 28-50kg; for standard projects, 55-80kg; and for large curtain wall/floor-to-ceiling windows, 95-180kg heavy-duty/sliding sliding supports. We have models available for everything from 400mm narrow windows to 3000mm ultra-high floor-to-ceiling windows. We completely solve window sagging, rusting, and poor closure problems for your building projects, reducing future maintenance costs.

Our grooveless sliding supports utilize a double-fixing structure combining a snap-lock mechanism and screws, ensuring even stress distribution. All supports undergo pull-out resistance testing before leaving the factory and are reinforced with SUS304 stainless steel. They comply with building exterior hardware standards and are stable and resistant to detachment even in strong winds.
For profiles with special grooves and arm lengths, if the purchase volume meets the standard, we can customize the size, open molds, and have the technical team check the profile samples in advance before production.
Standard small and medium-sized outward-opening windows come with two sliding supports, one at the top and one at the bottom. For heavy-duty windows weighing more than 80kg, it is recommended to select three. We need to provide the required number based on the window height and weight.
