STANDARD wedges / keys, pine, 50 pcs

      profile: 2.0 x 4.5 cm     side length 15 - 300 cm     custom formats possible on request     `sharp edge' possible on request The K 45 has a profile of 2.0 x 4.5 cm. We use seasoned and kiln-dried pine for the stretcher frame. The wood is finger-jointed to prevent the natural tendency of the wood to warp and, thanks to multiple gluing, is almost free of warping- a high-quality handcrafted product at an extraordinarily affordable price.The stretcher frame is available from a side length of 15 to 300 cm. We will be happy to cut the frame to your desired format for an additional charge of 5 euros per bar. Please note that the cross bars must also be cut to size.The stretcher frame has a round edge. If you wish a 'sharp edge', it is possible against a surcharge.In order to obtain a stretcher frame, you need two stretcher bars of the long side, two of the shorter side and optionally a middle piece or cross and wedges.The pine wood wedges necessary for wedging (2 pieces per bar and middle bar) are not included in the price. Please order https://peters-art.de/en/painting-supports/stretchers/wooden-stretchers/910/standard-wedges/keys-pine-50-pcs If you require an additional bracing, please combine the frame with the cross bars K 45: https://peters-art.de/en/painting-supports/stretchers/wooden-stretchers/12/cross-brace-k45-and-k40?number=10012The stretcher frame has a 1-fold slit from a side length of 50 cm up to a side length of 195 cm and a 2-fold slit from a side length of 200 cm.Advice on bracing:Under a side length of 50cm no middle bars are needed. If one side length exceeds 50cm, one middle bar of the shorter side length is sufficient.If both sides are more than 1m long, you need one bar per side length (a simple cross). If one side is more than 2m long, you need two middle pieces of the shorter side and one of the long side (single double cross). If both sides are more than 2m long, the stretcher bars are each double slotted, so you need two middle bars per side length (double double cross).

The middle bars K 45 are suitable for both stretcher frames K 40 and K 45.From 50 cm length one slit, i.e. a middle bars or a cross. From 2 m length two slots, i.e. two middle bars per side or a double double cross. Depending on the length, the centre pieces either have no slot at all (shorter than 50 cm length), only one slot (from 50 cm length) or 2 slots (from 2m length). Accordingly, further middle pieces should be added so that 2 of them interlock at each slot, forming a cross and thus stabilizing the frame. Matching slots are worked into the wedge frames to anchor the ends of the corresponding centre pieces there.The length of the center element should correspond to the length of the sidebar. Example: for a frame measuring 100x100 cm you need two center pieces in size 100 cm (simple cross).
