The roller measures 7\/8 inch in diameter and seats in a 3\/8-inch diameter plastic base. This guide keeps bifold door panels tracking correctly within the overhead track, preventing lateral drift and off-track binding. It is a direct hardware replacement installed by carpenters, general contractors, maintenance technicians, and experienced DIYers working on interior bifold door assemblies. The pack contains 2 roller guides.\u003c\/p\u003e\u003cp\u003eThis guide is suited for residential and light commercial bifold door installations. It mounts to the top edge of bifold door panels that are 1 inch to 1-3\/8 inches thick, covering the standard door thickness range found in most interior passage and closet applications. The spring-loaded design allows the roller to seat firmly into the overhead track without requiring precise vertical adjustment during installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpring-loaded roller maintains consistent contact with the overhead track\u003c\/li\u003e\n\u003cli\u003eNylon roller construction for smooth, low-friction operation\u003c\/li\u003e\n\u003cli\u003e3\/8-inch diameter plastic base mounts directly to the top door edge\u003c\/li\u003e\n\u003cli\u003eCompatible with door panel thicknesses from 1 inch to 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003ePack of 2 guides for a standard single bifold door unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for bifold door panels with a top edge thickness of 1 inch to 1-3\/8 inches.

Remove the door panels from the track before installing or replacing roller guides to avoid injury and to allow proper seating of the base into the door edge. Verify the overhead track slot width is compatible with the 7\/8-inch roller diameter before final installation. Re-hang the door panel and confirm the roller seats fully into the track before testing operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoller Diameter\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Door Thickness\u003c\/strong\u003e: 1 inch to 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoller Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoller Type\u003c\/strong\u003e: Spring-loaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 2 per pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.106 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRIME-LINE PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: N 6703\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRIME-LINE PRODUCTS","offers":[{"title":"Default Title","offer_id":51343067087154,"sku":"N 6703","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310550898.jpg?v=1782015494","url":"https:\/\/voomisupply.com\/products\/prime-line-products-n-6703-bifold-door-top-roller-guide","provider":"Voomi Supply","version":"1.0","type":"link"}
