The Chair Locks are the perfect choice to secure your dining/kitchen chairs so that your curious toddler cannot use them to climb and retrieve dangerous items. These straps anchor dining chairs right to the table, preventing tipping, climbing, and falls. Use them at mealtime, or keep chairs tethered full-time. Simply loop buckle strap onto chair and place lock end on table with included adhesive tape. Lock and unlock your dining chairs to table as needed. Releases with adult squeeze of latch. Works on wood or glass tables. Applies with double-sided non-marring adhesive . Length is adjustable. The Chair Locks may also be adjusted to secure toddlers in booster seats, keeping them snug to the table so they can't push out the chair or stand on the seat. Use 2 per chair. Comes with enough for 4 chairs.
