Installation Guide For: Defender® Opening Window Spikes

The Defender Opening Window Spikes™ allow the window to open without damaging the spikes and protect the window ledge from pigeons.

Each strip of opening window spike is 13 inches (1/3m) long. Maximum window sill protection is 8 inches (200mm).

This unique anti pigeon device attach's directly onto window frames that open outwards. Window spikes are delivered as a complete unit ready assembled. Simply screw the clips directly onto the window frame itself. If you do not want to screw the clip onto the window frame then remove spike from clip, glue clip to frame and leave for 24 hours before putting spike back into clip.

Every effort should be made to spike all possible landing sites that are 2 inches (5cm) or greater. Snap spikes into pieces to finish off rows or spike small areas. Spikes can be easily snapped using your fingers.

Window cleaners, contractors on ladders, scaffolders, painters etc. have a habit of damaging bird spikes. Warn them to be careful whilst working. A slightly damaged spike is likely to provide an ideal roosting or nesting spot for a pigeon. Any damaged spikes should be replaced before the pigeons move in.

Before starting the job, assess the work to make sure that you can do it safely and without hurting yourself or others. If you have any doubts at all then please contact us or return the spikes for a full refund - no questions asked. Wear suitable protective clothing, dust mask, gloves, overalls etc.
