The J top mount roller attaches to the top edge of each panel, leaving both door faces completely clear while the J-style roller arm remains visible above, maintaining the barn door aesthetic from the side.\u003c\/p\u003e\n\u003cp\u003eThis is a Goldberg Brothers heavy duty kit, made to order in Colorado with a limited lifetime warranty. Available in all 17 Goldberg Brothers powder coat finishes. Two 7 in pull handles are included — one per side. Ships in 10–15 business days. Total system weight capacity is 800 lbs across all four panels. For a fully clear opening, only 5 in of clear wall is needed on each side.\u003c\/p\u003e\n\u003cp\u003eIf the J-strap curve across the door face is part of your design intent, the \u003ca href=\"https:\/\/thebarndoorhardwarestore.com\/products\/j-strap-heavy-duty-4-door-bi-parting-bifold-barn-door-hardware-kit\" title=\"J-strap heavy duty 4-door biparting kit\"\u003eJ-strap heavy duty 4-door biparting kit\u003c\/a\u003e is the right choice.
