Frequently Asked Questions
Do I need to drill new holes to replace a shower door handle?
Only if your new handle’s center-to-center spacing doesn’t match the existing holes. Measure your current holes first (center-to-center and diameter). If they match one of the standard spacing options (18", 20", 24"), you can swap without drilling. If not, drilling tempered glass should be done by a professional to avoid cracking.
How do I stop a replacement handle from wobbling?
Wobble is usually a fit issue. Tighten the screws to the recommended torque and add rubber or silicone washers between the handle and glass to take up small gaps. Clear plastic sleeves or adhesive gaskets included with many Ranbo models also help center the bar and reduce movement.
What measurements matter when choosing a replacement handle?
The three critical measurements are: hole spacing (center-to-center), hole diameter (typically 1/2"/12mm for these models), and glass thickness (these handles fit 1/4–1/2" or 6–12mm). Also note finish and material to match existing hardware and ensure corrosion resistance in wet conditions.
