Frequently Asked Questions
Will a mounting kit stop my gate from sagging?
Yes — a properly chosen mounting kit or stabilizer keeps the gate frame square and reduces lateral stress on hinges and latches. Hardware mounts, wall cups and banister adapters all limit movement; choose a kit that matches your post width and gate height for best results.
Can I install a banister mounting kit without drilling into the post?
Many kits (including no-hole clamp systems and wooden protective adapters) are designed to avoid drilling into the post. Look for descriptions that explicitly state 'no screws into your post' or 'no-hole' mounting. Make sure the kit fits your post dimensions before purchasing.
How many mounting kits do I need for one gate?
Generally you need one mounting kit per post or per wall side you attach to. For a banister-to-wall setup you may need one kit on the banister side plus wall cups on the wall side — check the product description and included hardware to confirm exact needs.
