Hi KT, thank you for your inquiry. The robe hook has a weight capacity of up to 50 lbs. if toggle anchors are used and a weight capacity of up to 24 lbs. if self-drill or tile anchors used. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot!
Hi sa, We do not recommend mounting this hook on a hollow door. Due to the weight needed to support both the hook and the robes, it would damage the door and not be able to sustain the weight load. Thanks for your question!
