Keeping your terrace free of standing water and debris is crucial. WiseGuides® remove the guess work for precise gap spacing between terrace planks, which results in proper water drainage and drying. Build with striking, consistent lengthwise plank gap intervals time after time for professional results. The functional structure allows terrace installers to implement these spacers in any location between timber planks.

The exclusively crafted V-shape blade design and style prevents nicking as well as marring of hardwood, thermally modified woods and composite materials. Depending on the length of your terrace plank, place two or more spacer wedge tools every 60-70cm in between planks. Moving lengthwise between planks is a breeze thanks to the spacer's convenient handle. Let WiseGuides® spacer wedges remain in place during invisible fixing clip installation. Extract once installment is complete by effortlessly pulling the handle upward, releasing it from the plank gap.

Guarantee Precise & Regular Gaps

The specially made V blade design and handle of WiseGuides® gap spacer wedges help thwart damage to terrace timbers that pressed together during installation. Thanks to the unique handle design, no more loss of time due to wedges that are impossible to remove between two tightened planks.

The extreme hardness of the hardened plastic wedges guarantee they will keep their normal thickness, even after the planks have been secured.
