Kit de remplacement ressorts de torsion
Ils sont un peu rêveurs au service expéditions chez Spadone. Il a fallu 3 envois pour que la commande soit complète! Il n'en reste pas moins que le kit est bien conçu et le matériel de qualité. La pose demande un peu d'adaptation au type de porte rencontré et s'adresse plutôt à des bricoleurs avertis. Au final le système est beaucoup plus facile à utiliser et à régler que les systèmes à ressort de torsion. Je recommande ce produit.
