holding wiring in place for a small child busy box
I use PL400 for everthing that needs this kind of strength with a dot and works much better than hotglue which is good for large surfaces but not small wires. Set time is 15 minutes but takes a day to cure and several days for full strength. 

Waterproof and weather resistant, great for indoor and outdoor use
Cold weather gun-ability eliminates roll up on wet and frozen lumber
Meets and exceeds APA AFG-01 specs
Gap filling properties help to bridge minor gaps when bond irregular surfaces, reducing squeaking and splitting
High grab formula reduces the use of fasteners
Provides a strong durable bond to multiple surfaces
Low VOC formulation meets stringent State and Federal VOC regulations
Bonds dry, wet, frozen and treated lumber to most building materials
